A charged particle moving in a constantmagnetic field always experiences a magnetic force, regardless of its direction of motion. • may experience a magnetic force which will cause its speed to change. • may experience a magnetic force, but its speed will not change

A charged particle moving in a constant magnetic field may experience a magnetic force but its speed will not change.

Explanation:

The magnetic force experienced by a charged particle q that moves in a magnetic field with velocity is:

and its magnitude is given by:

where is the angle between the magnetic field and the velocity.

There are two special cases:

The magnetic force is always perpendicular to the velocity. The work done by the magnetic force is equal to the force multiplied by the displacement in the direction of the force:

Given that the work is equal to the change in kinetic energy and this means the speed will not change.

answer: he got 23

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
