If you strike a sharp edge of a metallic knife against the north pole of a bar magnet,it will induce a north pole.

In order to find the force experienced by a current-carrying conductor,we can use Maxwell's corkscrew rule.

Explain the meanings of the words "electromagnetic" and "induction" in the term electromagnetic induction. List three factors on which the value of induced current produced in a circuit depends. Name and state the rule used to determine the direction of induced current. State one practical application of this phenomenon in everyday life.

What is the frequency of $DC$ (in $Hz$)?

Define a solenoid. How is it different from a coil?

Name and state the rule to determine the direction of a force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it. Name a device that uses a current-carrying conductor and a magnetic field.
