The idea that static magnetic fields might have a therapeutic value has been around for centuries....
Magnetic Field. I have no idea how to solve these questions, please help!!!! MAGNETIC FIELDS SUMMARY You will measure how the magnetic field, B, produced by a coil varies with the current, I, in the coil. From your measurements, you w calculate the permeability constant Ho. Lastly you w use a magnet to induce a voltage in the coil. THEORY The magnetic field Batthe center of a circular coil (solenoid) of radius R with N turns that carries a current...
There has been some concern in recent years over the possible health effects from magnetic fields generated by transmission lines. Suppose a transmission line is suspended 19 meters overhead by a tower and carries 1,666 A of current. The Earth's magnetic field on the surface is approximately 5.0 Times 10^-5 T. What percentage of the Earth's magnetic field is the field produced on the ground by the transmission lines? In the previous question, what can you say about the dangers...
