A loop of wire has a resistance 362 Ohms and an area of 2.91 m2 . The wire loop is located in a magnetic field which is perpendicular to the plane of the loop. The magnetic field has the following time dependence: B=B0 exp(-b*t) where t is time. b =0.45Hz. The current is 0.00631 Amps at time 0.79s. Find B0 in units of Tesla. (Note that both B and B0 are magnitudes i.e. positive.)

A rectangular loop with sides a and b (b> a) consists of a wire whose resistance can be neglected and has a mass of self-inductance L. The loop moves initially with speed of module v_0 along the longest side and passes through a region with zero magnetic field to another with uniform magnetic field of module B_0, perpendicular to its plane. Therefore, for this turn, determine: a) speed as a function of time. b) the position as a function of...

A flat coil of wire has an area A, N turns, and a resistance R. It is situated in a magnetic field, such that the normal to the coil is parallel to the magnetic field. The coil is then rotated through an angle of 90˚, so that the normal becomes perpendicular to the magnetic field. The coil has an area of 1.5 × 10-3 m2, 50 turns, and a resistance of 190 Ω. During the time while it is rotating,...

The illustration below shows a loop of wire with area A and a uniform magnetic field B that goes through the loop. (The field fills the whole area of the page, but it is simpler to make one drawing.) The area vector and B-field direction are both in the plane of the page. The loop is perpendicular to it, but drawn in a perspective view so that you can see it is a loop. The B-field has a constant magnitude...
