What happens if a full circular ring is used instead of a split ring (commutator) in an electric generator?

When the direction of electric current in a conductor is perpendicular to the direction of the magnetic field,what is the magnitude of the force acting on the conductor?

Differentiate between overloading and short-circuiting.

State the direction of the magnetic field inside the bar magnet.

$A$ current $I$ passes through a circular loop $C$ and a solenoid $AB$ as shown below:
$(i)$ What is the polarity of: $(a)$ the face of the loop you are looking at? $(b)$ the end $B$ of the solenoid?
$(ii)$ What is the direction of the magnetic field at the centre of the loop?

$A$ student,while studying the force experienced by a current-carrying conductor in a magnetic field,records the following observations:
$(i)$ The force experienced by the conductor increases as the current is increased.
$(ii)$ The force experienced by the conductor decreases as the strength of the magnetic field is increased.
Which of the two observations is correct and why?
