WebFind the current in a long straight wire that would produce a magnetic field twice the strength of the Earth’s at a distance of 5.0 cm from the wire. Strategy The Earth’s field is about 5.0 × 10 − 5 T, and so here B due to the wire is taken to be 1.0 × 10 − 4T. The equation B = μ0I 2πr can be used to find I, since all other quantities are known. WebMagnetic fields can only exert a force on a moving charge. In physics, a magnetic field is represented by the letter “B”. The standard MKS unit for a magnetic field is Tesla. A Tesla is 1N/amp*m. Magnetic fields can also be measured using the unit of gauss. One gauss is equal to 1 x 10-4 Tesla. There are many different sources of magnetic ...
