The magnetic field of the Earth is similar in shape to that of a bar magnet, as shown in the figure. If a proton from space enters the Earth's magnetic field to the left of the Earth, with a velocity of 8x107 m/s directed into the page, and the Earth has a magnetic field strength of 1x10-5 T at this location; a) What is the magnitude of the force acting on the proton? b) What is the direction of the force acting on the proton? c) What is the radius of the resulting circular trajectory that the proton will follow?

A square coil of wire carries a current of 3.11 A. The coil has 340 turns and has a side length of 0.71 m. If the coil is placed in a magnetic field and the maximum torque the field can apply to the coil is 1.23E+03 N*m, what is the strength of the magnetic field? (Answer in T).

A solenoid has 7,635 turns, a length of 74.1 mm, and a radius of 2.77 mm. What is the strength of the magnetic field at the center of the solenoid if it carries a current of 865 amps?

a toy train uses a magnetic field to propel it down a track. A series of flat, permanent magnets align the length of both rails of the track. In place of wheels, the train rides an axle that lays across the track. A current flows through the axle at all times. In which direction must the poles of the permanent magnets face in order to propel the train down the rails?
