A small square loop of wire carrying some current is located between the poles of a horseshoe mag- net as shown in the diagram. Throughout this problem you may assume that the magnetic field between the poles is constant. Note that the loop is shown skewed only to pro- vide some perspective. When the loop is vertical, its face is actually parallel to the poles of...

A circular loop of wire of radius R carries a current I in a region where a uniform magnetic field of magnitude B0 is present. (a) If the magnetic dipole moment of the loop makes an angle θ < π/2 with the magnetic field, do a drawing that includes the loop of current, its magnetic dipole moment, the magnetic field, and the direction of the torque experienced by the loop. Make sure to indicate the current i and the angle...

Force between an Infinitely Long Wire and a Square Loop
A square loop of wire with side length a carries a current I1. The center of the loop is located a distance d from an infinite wire carrying a current I2. The infinite wire and loop are in the same plane; two sides of the square loop are parallel to the wire and two are perpendicular as shown.

A very long wire and a square loop of wire lie in the plane of the page as shown. Each side of the square is 15 cm in length, the resistance of the loop is 0.6 Ω, and the near side of the loop is 3 cm from the long wire. The current in the long wire is to the right and is increasing. At the moment, the current in the long wire is 6.5 A. The magnetic flux through...

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,...
