A square loop of wire with a small resistance is moved with
constant speed from a field free region into a region of uniform B
field (B is constant in time) and then back into a field free
region to the left. The self inductance of the loop is
negligible.
When entering the field the coil experiences a magnetic force to
the left.
When leaving the field the coil experiences a magnetic force to the
right.
Upon entering the field,...

Magnetism 1. (4) An unknown particle travelling at a velocity of 2.20x106 m/s to the right as seen by an observer, enters a region that has an electric field of magnitude 750 V/m pointed away from the observer. Ignore gravity for this question. (a) What is the direction and magnitude of the perpendicular magnetic field which would best cancel out the effect of the electric field so that the particle passes through undeflected? (b) If while travelling 0.200 m, with...

A rectangular loop of wire with dimensions and w is released from rest at time t = 0 from a region with zero magnetic field into a region with uniform magnetic field Bo pointing into the page. At t=0, the upper edge of the loop is in the zero field region and the lower edge is in the uniform field region as shown in the figure below. The loop has mass m and the acceleration due to gravity is g...

3. Electromagnetic Inductance. Consider a single loop under magnetic field. (a) If the area A = 0.012[m) is constant, but the magnetic field is increasing at the rate of 0.020 T/s), determine the induced emf. (Use Faraday's law; the induced emf in a loop equals the absolute value of the time rate of change of the magnetic flux through the loop.) (b) If the total resistance of the circuit is 5.0(82), find the induced current. (c) Suppose we change the...

Group Problem 1. A conducting bar with mass m and resistance R slides on frictionless conducting rails, separated by a distance 1 from each other, in a region that has a static uniform magnetic field B directed into the page (see figure below). An external agent is pushing the bar, maintaing its motion to the right with constant velocity ū. At time t = 0, the agent abruptly stops...
