What is the causes of electromagnetic induction?
Change in magnetic flux.iechange in magnetic field (B).change in the area vector/ area of magnetic field under the closed circuit (A).The angle between area vector and magnetic field .......xomagnetic flux = cosxo . A . B
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current
Are the magnetic field lines open or closed curves?
closed curves.
WHAT happens when you run salt water through a magnetic field?
You can use a magnetic field to move salt water. Magnetohydrodynamics.

What happens to the magnetic field of wire when you change the direction of a current of the wire?
In that case, the magnetic field will also be reverted.

The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
What happens to magnetic field of a wire when you change the direction of the current in the wire?
Direction of the magnetic lines too would get changed

Are the magnetic field lines open or closed curves?
closed curves.
Is earth's magnetic field in an closed iron box more than the magnetic field outside the box?
No
What happens when white light passes through a strong magnetic field?
I have the impression that light is not affected by magnetic fields - at least in a vacuum. If traveling through other substances, the magnetic field can change the light's polarization.
Which direction does magnetic fields flow?
I think it is a mistake to refer to magnetic field 'flowing. Magnetic fields just are, they can change, and these disturbances might move in space, but the field itself does not flow. That being said, and assuming you meant to ask in which direction a magnetic field points the answer is that a magnetic field points towards the south pole of a magnet and away from the north pole. A magnetic field cannot be divergent (i.e. there are no sources) and any field line must be closed.
What happens when the magnetic field or or more magnets overlap?
they combine and become one magnetic field
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
