Magnetic Fields and Wire Interactions

The video tutorial demonstrates the interaction between DC current, a coil, and a wire. It explains how a DC current through a coil creates a magnetic field and how a straight wire generates a circular magnetic field. The tutorial shows the wire wrapping around the coil due to magnetic attraction and repulsion, and how reversing the magnetic field changes the direction of the wire's movement.

What happens when DC current is sent through a wire in relation to a coil?

• It creates a magnetic field that repels the coil.

• It creates a magnetic field that attracts the coil.

• It creates a straight up or down magnetic field.

• It creates a circular magnetic field.

How does a straight line wire affect the magnetic field?

• It creates a straight magnetic field.

• It neutralizes the magnetic field.

• It creates a circular magnetic field.

• It amplifies the magnetic field.

What is the effect of a circular magnetic field created by a wire?

• It attracts the coil.

• It repels the coil.

• It causes the wire to wrap around the coil.

• It causes the wire to straighten.

What is the result of reversing the magnetic field?

• The wire wraps in the same direction.

• The wire stops moving.

• The wire wraps in the opposite direction.

• The wire creates a new magnetic field.

What happens when the switch is thrown to reverse the magnetic field?

• The wire remains stationary.

• The wire wraps around the coil in the same direction.

• The wire wraps around the coil in the opposite direction.

• The wire creates a new coil.
