$A$ metallic ring connected to a rod oscillates freely like a pendulum. If now a magnetic field is applied in a horizontal direction so that the pendulum now swings through the field,the pendulum will

Consider a metallic pipe with an inner radius of $1 \ cm$. If a cylindrical bar magnet of radius $0.8 \ cm$ is dropped through the pipe,it takes more time to come down than it takes for a similar unmagnetised cylindrical iron bar dropped through the metallic pipe. Explain.

The use of eddy currents is done in the following,except:

$A$ metal detector works on the principle of:

When a small magnet is allowed to fall through an aluminium pipe,it falls with an acceleration less than $g$. Why?

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: $A$ bar magnet dropped through a metallic cylindrical pipe takes more time to come down compared to a non-magnetic bar with same geometry and mass.
Reason $R$: For the magnetic bar,Eddy currents are produced in the metallic pipe which oppose the motion of the magnetic bar.
In the light of the above statements,choose the correct answer from the options given below:
