Question

A straight, vertical wire carries a current of 1.23 A downward in a region between the poles of a large superconducting electromagnet, where the magnetic field has a magnitude of B 0.557 T and is horizontal. (a)What is the magnitude of the magnetic force on a section of the wire with a length of 1.00 cm that is in this uniform magnetic field, if the magnetic field direction is east? (b)What is the direction of the magnetic force on a section of the wire with a length of 1.00 cm that is in this uniform magnetic field, if the magnetic field direction is east? ANSWER: south north west east

Explanation / Answer

F = ILB

F = 1.23 * 1*10^-2 * 0.557

F = 6.8511 x 10^-3 N

b )

towards south (using right hand rule )
