Question

Question 1 (1 point)

True or False: An induced magnetic field in a wire opposed the change in the external magnetic field

Question 1 options:

Question 2 (1 point)

True or false: Changing an electric field can produce a magnetic field.

Question 2 options:

Question 3 (1 point)

To determine the direction of the magnetic field, ______.

Question 3 options:

Place the thumb of your right hand along the direction the ELECTRONS are travelling and curl your fingers.

Place the thumb of your right hand along the direction the CURRENT and curl your fingers

Currents do not generate magnetic fields.

The magnetic field points radially outwards at all points from a current-carrying wire.

Question 4 (1 point)

If you long current carrying wires are parallel to each other with current travelling in the same direction, the wires will ____________

Question 4 options:

Not interact

Be pushed away from each other.

Be attracted to each other.

Have their magnetic fields cancel out completely everywhere in space.

Question 5 (1 point)

Two long parallel wires are separated from each other by a distance of 10 cm. The current running through each wire is in the same direction and has a magnitude of 3A. What is the magnitude of the field from one wire at the other one?

Question 5 options:

0.00003 T

0.000003 T

0.00006 T

0.000006 T

Question 6 (1 point)

Two long parallel wires are separated from each other by a distance of 10 cm. The current running through each wire is in the same direction and has a magnitude of 3A. If the wires each have a length 10m (i.e. relatively long), what is the approximate force one wire exerts on the other?

(Hint: The charge in a segment of wire is the current times the length)

Question 6 options:

0.00006 N

0.00018 N

0.006 N

0.0018 N

Question 7 options:

Clockwise

Counterclockwise

There is no induced current

Something else

Question 8 (1 point)

If the magnetic field begins decreasing, an induced current will generate a field

Question 8 options:

In the same direction as the external field

Opposite the direction of the external field.

There is no induced current

Something else

Question 9 (1 point)

If the magnetic field begins increasing, an induced current will generate a field

Question 9 options:

In the same direction as the external field

Opposite the direction of the external field.

There is no induced current

Something else

Question 10 (1 point)

If the external field is turned off and a bar magnet drops through the loop of wire, the induced field from the wire will

Question 10 options:

Be in the direction the magnet is falling the entire time

Be opposite to the direction the magnet is falling the entire time.

There is no induced field

Switch directions as the magnet is halfway through the loop.
