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

Under what condition does a current-carrying conductor kept in a magnetic field experience maximum force? On what other factors does the magnitude of this force depend? Name and state the rule used for the determination of the direction of this force.

Why does a current-carrying conductor kept in a magnetic field experience a force? On what factors does the direction of this force depend? Name and state the rule used for the determination of the direction of this force.

$(a)$ Name two electrical appliances of daily use in which an electric motor is used.
$(b)$ Name and state the principle on which an electric motor works.

Mention the angle between a current-carrying conductor and a magnetic field for which the force experienced by this conductor is maximum. (in $^{\circ}$)

An electron enters a uniform magnetic field at right angles to it as shown in the figure below. In which direction will this electron move? State the rule applied by you in finding the direction of motion of the electron.
