Magnetic Field Strength

Question 1

Magnetic force has a ___ and ___ pole, where ___ always travels south

Answer 1

North and south
north travels south

Question 2

During magnetic field interactions what does the x’s and dots mean.

Answer 2

x = into the page
dots = out of the page

Question 3

what happens when you move a charge in the magnetic field?

Answer 3

moving charges create magnetic fields. Therefore, magnetic field can interact with external fields resulting in the charge experiencing force.

Question 4

If the charge is moving parallel to the field there is ___ magnetic force on the charge.

what is the formula used

Answer 4

No

Question 5

When can you apply circular motion to magnetic fields?

Answer 5

when a moving particle is perpendicular to the net force, we can apply circular motion.

Question 6

How to find the magnetic field around a wire?

Answer 6

we find the force exerted on a straight current carrying wire in a magnetic field using the formula:
