How do the directions of the magnetic field lines about a current-carrying wire shown?
They are directed away from the wire in all directions.
They are parallel to the wire and similar to the direction of the current.
They form a pattern of concentric circles around the wire.
They are parallel to the wire but opposite to the direction of the current.

What happens to the direction of the magnetic field about an electric current when the direction of the current is reversed?
It stays the same.
It becomes parallel to the current-carrying wire.
It points away from the current-carrying wire.
It becomes reversed.
If a wire carries a certain amount of current, how can the magnetic field strength be increased due to this current?
by allowing the current to alternate its direction periodically
by making multiple loops out of this wire
by increasing the length of the wire
by placing the wire in a vacuum
In what direction relative to the magnetic field does a charged particle move in order to experience a maximum deflecting force?
It should be moving parallel to the magnetic field but opposite in direction.
It should be moving perpendicular to the magnetic field.
It should be moving parallel to the magnetic field and in the same direction.
It should be stationary and within the region of the magnetic field.
Two current-carrying wires are placed close to each other as shown in the figure on the right. What would be the effect if both wires were carrying current in the same direction?
Both wires will experience an attractive force towards each other.
The wires will deflect each other until they become perpendicular to each other.
Both wires will experience a repulsive force away from each other.
The wires have no effect on each other.
A beam of electrons is directed towards a region in between two magnetic poles as shown in the figure below. What would happen to the electron beam as it passes through the magnetic field?
The electron beam would be deflected and travel back to its origin.
The electron beam would be deflected and travel in a parabolic path out of the page.
The electron beam would be deflected and travel in a parabolic path downward.
The electron beam would be deflected and travel in a parabolic path upward.
A current-carrying wire passes through a magnetic field as shown in the figure below. What would be the effect of the magnetic field on the wire?
The wire will be pushed up
The wire will be pushed down.
The wire will be attracted to the north pole of the magnet.
The wire will be attracted to the south pole of the magnet.
A proton moves into a region of magnetic field where the field lines are perpendicular to the motion of the proton and directed into the page as shown in the figure below. If the proton remains within the magnetic field region after a certain amount of time, how did the magnetic field affect the motion of the proton?
The proton is slowed down until it comes to a full stop.
The proton will move in a circular path with a clockwise direction.
The proton will oscillate in a simple harmonic motion.
The proton will move in a circular path with a counterclockwise direction.
An electron moves horizontally in between two electrically charged plates as shown below. How will the path of the electron be affected as it goes through the field?
The electron will move in a straight line undeviated.
The electron will be deflected to a direction out of the page.
The electron will be deflected upward in a projectile motion.
The electron will be moving in a circular motion in the clockwise direction
I decided on physics between all science subjects (in Grade 11) because it was the most general of all sciences. In our physics lessons I do not need memorization everything, but i like to think of the way thing worked in terms of physical laws and algorithms, that's why I ........................... all physics lessons
