Upwards
Downwards
Left
Right
According ot the givens, no force exists.
3A lightning bolt hits the ground vertically transfering negative charges from the sky to the ground. What is the direction of the b-field to the right of strike if the slightning bolt lands directly in front of you?
From behind to in front of you
From in front of you to behind you.
From your right to your left.
From your left to your right.
4A wire feels a force downwards of 2 newtons. The wire is in a magnetic field pointing from front to back. What is the direction of the current in the wire?
Traveling to the left.
Traveling to the right.
Traveling from behind you to infont of you.
Traveling from in front of you to behind you.
(1) Are you using your RIGHT hand. (2) Electrons travel the oppisite direction of the defined current. Using the CLOSED RIGHT hand rule, your thumb should be pointing forwards.
5A wire is carrying electrons from in front to behind you. What is the direction of the magnetic field on top of the wire?
To the left
To the right
From the floor to the ceiling
From the ceiling to the floor
Either the answer cannot be determined from situation or this is impossible.
6A wire is connected to a battery. Imagine the wire is stetched in front of you in the air. If the magnetic field over the top of the wire is pointing towards you, then where is the positive pole of the battery connected to this wire?
In front of you
Behind you
At your left side
At your right side
Either the answer cannot be determined from situation or this is impossible.
7A wire is placed between the poles of a magnet. The magnet's b-field is pointing from the right to the left. The wire is levitated upwards. What is the direction of the current?
From in front to behind you.
From behind to in front of you.
From your left to your right.
From your right to your left.
Either the answer cannot be determined from situation or this is impossible.
8A wire current is running through a wire from right to left. The wire is placed in a magnetic field that is running from left to right. What is the direction of the force on the wire?
The force is pushing the wire upwards.
The force is pushing the wire downwards.
The force is pushing the wire to the right.
The force is pushing the wire to the right.
Either the answer cannot be determined from situation or this is impossible.
