Question

Units of a magnetic field might be:

A) C-m/s
B) C-s/m
C) C/kg
D) kg/C-s
E) N/C-m

Answer 1

The correct unit for a magnetic field is N/C-m, representing newtons per coulomb-meter, which corresponds to option E) N/C-m, and the SI unit for magnetic field strength is the tesla.

Step-by-step explanation:

The SI unit for magnetic field strength B is the tesla (T). The correct option that corresponds to the units of a magnetic field is N/C-m, which can also be written as newtons per coulomb-meter. This is derived from the force equation F = q(v × B), where F is force, q is charge, v is velocity, and B is the magnetic field. Since 1 Tesla (T) is equivalent to 1 Newton per coulomb-meter per second (1 T = 1 N/C-m/s), answer E) N/C-m is the correct choice. Other notable units include the gauss (G), where 1 G = 10-4 T. The direction of the force on a moving charge in a magnetic field is given by the right hand rule 1 (RHR-1).
