PLZ help I'm so Lost
which object does not generate a magnetic field in the space around it?
A bar magnet
an electron moving around the atomic nucleus
electric current traveling through a wire
a stationary point charge

1. Direction of B is parallel to V

2. Magnetic field is most uniform between the flat, parallel magnetic poles of a c-shaped magnet

3. Doubling B would double the magnitude of the force on the proton

4. Magnetic field is strongest near the north and south poles

5. The initial direction of the proton is toward the right of the screen. The field deflects the proton toward the top of the screen

6. Assume that you are viewing the diagram on a flat computer screen. Perpendicular to the screen, pointing toward you.

7. A stationary point charge doesn’t generate a magnetic field in the space around it.

8. Proton enters magnetic field at a speed of 7.8 x 10^4, charge of proton equal to 1.6 x 10^-19 is 2.6 x 10^-14 N

9. A few times every million years

10. Magnitude |q|vB directed towards bottom of screen

Explanation:

need to see circuit to get time constant

we need to know the time interval during which the force acts. impulse of force = momentum change
