If you place the North pole of a magnet next to the South pole of another magnet, they will:
Attract
Repel
Do nothing
Shatter
Why does a compass needle point north?
Because it is being attracted to the Magnetic South Pole
Because north is up
Because it is being attracted to the Magnetic North Pole
Because north is down
Unit for magnetic field strength, B
Weber (Wb)
Henry (H)
Tesla (T)
Tesla per meter square (Tm2)
To determine the direction of the magnetic field in a straight wire, we use:
Fleming right-hand rule
Fleming left-hand rule
Left-hand grip rule
Right-hand grip rule
If two magnetic North poles are brought near each other, what would the magnetic field lines look like?
the lines would connect between the poles
the lines would move out, but then curve away from each other
the lines would curve like an "S"
since South poles repel, there would not be any lines
Magnitude of magnetic field produced in a circular coil increase when:
Reduce the radius of the coil
Increase the radius of the coil
The current flow is reduced
The current flow is reversed
Using Fleming's left hand rule, the direction of the magnetic field, B on a current carrying conductor is:
Thumb
First finger
Second finger
Third finger
When a charged particle enters a perpendicular uniform magnetic field, it experience a _______________ because of the ____________.
Circular motion, magnetic force
Circular motion, centripetal force
Projectile motion, magnetic force
Projectile motion, centripetal force
How would you calculate the force on a moving (at right angles) charge in magnetic field?
F = BIL
F = qvB
F = Eq
This is no force
How could you increase the strength of a magnetic field in a solenoid?
use an iron core, decrease the number of turns of wire
increase the voltage and decrease the number of turns
use an iron core and increase the size of the current
increase the number of turns and decrease the current
A wire carries a current, creating a magnetic field around itself as shown. The current in the wire is:
Directed to the right
Directed to the left
Into the page
Out of the page
A wire carries current I directed to the right as shown in the figure below. What is the direction of the magnetic field generated by the wire at point A?
To the right
To the left
Toward the wire
Into the page
