  • Making an Electromagnet Check us out at How to Make an Electromagnet As the name suggests, electromagnet is made with the help of electricity. The advantage of the electromagnet is that, the magnetic field of the magnet can be expanded and also can be made more powerful by using a comparatively light, less costly material and a small amount of electricity. The following is a process of the making of a simple electromagnet. This kind of magnet can also be made by you at home and can also be taken up as a small science experiment by school going children. It must be noted that this magnet can only be used to attract metallic objects of a light weight. Requirements To make an electromagnet all you need is a 9 volt battery, a couple of 3 inch iron nails and a piece of insulated copper wire. Procedure The procedure of making the electromagnet is relatively simple. First, remove about half an inch of insulation form both ends of the copper wire. Then systematically coil and envelop the nail with the help of the copper wire. Remember to follow a systematic pattern while wrapping the copper wire. The coils or wraps should not overlap each other. Fix one end of the copper wire, on the positive terminal of the battery and the other end to the negative end. When the circuit of the copper wire is complete, the nail will get activated and will start attracting other metallic objects. One can test the magnet with the help of the other nail. You can also lift the nail up by using the ...

  • Avoid ElectroMagnetic Field Radiation EMFS Part 1 Cordless Phones Health Rsks : Blue tube headset : INSTALL EMF/EMR FILTERS AND CAPACITORS on electrical circuitry in your home. Electromagnetic fields are constantly riding on the wiring and electrical devices in your home. These filters harmonize the electromagnetic fields (EMF) and electromagnetic interference (EMI) on the wiring and reduce your exposure. WEEP does not sell or promote any particular brand of filter but you can find plenty of information on the internet. You will need filters that work in the 4kHz to 100kHz range. CHECK THE WIRING IN YOUR HOME to make sure all connections are secure and there is no breakage anywhere. CHECK ALL ELECTRICAL APPLIANCES to ensure they are in perfect working order. Do not break off the ground prong on the plugs. CHECK THE OUTSIDE CONNECTION TO THE MAIN POWER LINES Call your electric utility provider and have them check to make sure they are all secure and there is no breakage anywhere. Also have them trim tree branches around the supply cable so they don't touch and create surges on your line. ANOTHER MAJOR SOURCE OF EMFs IS GROUND CURRENT ENTERING YOUR HOME ON WATER AND GAS PIPES. Install a dielectric coupling (electrically insulating piece) after having it checked by a licensed electrician. Replacing copper pipe with PVC can also reduce the transmission of EMFs around the home. OTHER CONSIDERATIONS Because metal is an ideal transmitter and reflector of electricity and electromagnetic radiation ...

  • science project - electromagnetic flux Two solenoids made of single-strand copper wire wound on wooden spools with a large-head iron nail as the plunger are placed alongside. The solenoids are connected in series and powered by 6V DC source. When the coils are energized an induced electromagnetic field is produced and magnetize the plungers creating magnetic pole on both ends. The plungers attract each other because of opposite poles. When the power connection of one of the solenoids is reversed, the plungers repel each other. This project demonstrates electromagnetic flux can be produced by direct current, using copper wire and ferrite material. There are many industrial control and switching circuitry applications using electromagnetic force.
  • "Antigravity" method 10b of 15 Electromagnetic suspension with feedback Group IIIA Filmed 1991-1996, 10b of 15methods of levitating an object known to the author John Iwaszko, edited from the video Antigravity the reality made in 1996. The antigravity method shown in this edit, at the time was classified as Method 10 of 15, Electromagnetic Suspension-repulsion or attraction with feedback loop control, Group IIIA. It is well known that the attraction from a permanent magnet decreases with increased distance, and increases at closer distances, which is 'unstable', unless tethered or pivoted or rotated such as shown in methods 5, 6 and 9. It is also possible to create a stable system by using the opposite principle by varying the magnetic field of a permanent magnet or a dc powered electromagnet that will push a permanent magnet back to a stable position. Stable magnetic levitation can be achieved by electronic control circuitry that can measure the position and speed of the object being levitated, and using some type of feedback system which continuously adjusts one or more electromagnets to correct the object's motion, thus forming a servomechanism, and although a direct current supplies the electromagnet the power, the electromagnet oscillates between off and on state and also switch between polarity so has been grouped with alternating AC current levitation, also called Electromagnetic suspension (EMS), and is successfully controlled by a correct position of the sensor or sensors utilised as well, as exact current control such as driving the ...

  • Electromagnetic Therapy Offers Hope for Depression Although several therapies exist for people with severe clinical depression, including medication, psychotherapy and electroconvulsive therapy, they don't all work for everyone. For many patients with severe depression — characterized by an all-encompassing low mood and loss of interest or pleasure in normally enjoyable activities — who have tried without success to relieve their symptoms with at least one round of medication, there now is a therapy that stimulates the brain, but does so without general anesthesia or lingering aftereffects. Called transcranial magnetic stimulation (TMS), the procedure uses magnetic fields to change the activity in a specific area of the brain thought to influence mood and emotion to improve the symptoms of severe depression, explains Ian Cook, MD, director of the UCLA Depression Research and Clinic Program. The procedure is conducted in an office setting; a patient undergoing TMS sits in a chair resembling a recliner, while a large electromagnet is precisely positioned over his or her head to emit targeted electromagnetic pulses. While the patient's head is gently secured in place, he or she is fully awake during the 45-minute sessions and is able to read, converse, watch videos or listen to music. The therapy is conducted five days a week over four to six weeks. "Some people like to take a nap. Others like to meditate. All they really experience is the sensation of a tapping on the scalp from the magnetic field, even though nothing is ...

  • Electromagnetic Levitation System Please visit for more information. The electromagnetic levitation system is available as a kit or fully assembled unit. This system uses an electromagnet to levitate a small magnet in midair. The small magnet levitates in the air indefinitely without any disturbance. The air gap is about 2 cm (3/4"). The supply voltage is 5 V and the supply current is about 0.3 A. The vertical position of the levitating magnet is measured using a linear Hall effect sensor and the current in the electromagnet is actively controlled using a dsPIC30F3012 digital signal processor. Three push buttons are included to adjust the vertical position of the levitating magnet and to apply a sinusoidal, square or sawtooth reference signal. Both the amplitude and frequency of the reference signal can be adjusted using the push buttons. questions or comments? contact us at [email protected]
