Let's apply the torque equation to a circular coil of wire in a magnetic field. The coil has an average radius of 0.0435 m , has 40 turns, and lies in a horizontal plane. It carries a current of 7.25 A in a counterclockwise sense when viewed from above. The coil is in a uniform magnetic field directed toward the right, with magnitude 1.05 T . Find the magnetic moment and the torque on the coil. Which way does the coil tend to rotate

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
