A current is applied to an object, such as a wire. What is true about the scenario?
A magnetic field is created.
The gravitational field is doubled.
Magnetic force is created in the direction of the object.
A moving charge opposite to the direction of the object is created.
Two wires carry equal amounts of current out of the page as in the image shown. What is the magnetic field at the point exactly between the two wires?
The magnetic field is 2x stronger compared to that of one wire, magnetic field going out of the page.
There is no magnetic field.
The magnetic field is 2x stronger compared to that of one wire, magnetic field going into the page.
The magnetic field acting upon the point is of the same magnitude on both sides
A 3cm long wire carrying 2A of current is inside a magnetic field of 4 Teslas. What is the magnetic force on the wire?
24N to the right.
24N out of the screen (Towards you).
0.24N into the screen. (Direction you are facing)
There is no force.
Which of the following is true?
A current creates a magnetic field.
A magnetic field creates a current in a wire.
A change in magnetic field creates a current in a wire.
Like sides of a magnet attract.

The magnetic field of an object is always proportional to...
How long a current has been running through the object.
The magnitude of the resistance the object is giving.
The magnitude of the current running through the object.
The amount of geese it touched that day.
When deriving the magnetic force, which of the following variables are needed?
F for Force.
μ for friction.
q for current.
r for distance between the two magnetic fields.
q for magnetic charge of the poles.
How does the coil concentration affect the strength of an electromagnet similar to the one in the demo?
More coils - Less strength
Less coils - Less Strength
Higher wire gauge - More strength
Lower wire gauge - More strength
