    The size of the magnetic force on a straight wire of length L carrying current I in a uniform magnetic field with strength B is F=ILBsin(?). Here ? is the angle between the direction of the current (along the wire) and the direction of the magnetic field. Hence Bsin(?) refers to the component of the magnetic field that is perpendicular to the wire, B?. Thus this equation can also be written as F=ILB?. The direction of the magnetic force on...

    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,...
