How to find the magnetic force on and acceleration

Topic:-Magnetic force on and Acceleration

A magnetic field is a vector field which surrounds magnets and electric currents, and is detected by the force it exerts on moving electric charges and on magnetic materials and acceleration is the change in velocity over time.

Let's see how these two works along with each other in the following problem.

Question:-

If we have an 8.2A current running through a 0.012meter wire, with a magnetic fields strength of 1.2T, what would be the direction of the force and what would be the acceleration of the 0.32kg wire? Find the net force, direction and acceleration?

ANSWER:

This physics help explanation is based direction of force.

Net force=0.11808N, Acceleration=.01296*10³¹ m/sec²

Here,

I=8.2A

Mass= 0.32kg

L =0.012meter

B=1.2T

F=BIl sinθ, here θ=90, so sinθ=1

Force on a current carrying wire of length l is=0.11808N

F is perpendicular to both E and B

Acceleration=F/m= .01296*10³¹ m/sec<sup>2
