Difference between translational and rotational acceleration of a conducting loop?

Translational: Loop moves in a straight line. Rotational: Loop spins or rotates.

Compare the effect of a weak vs. strong magnetic field on induced current.

Weak field: Lower induced current. Strong field: Higher induced current.

Compare magnetic force and electric force.

Magnetic Force: Acts on moving charges. Electric Force: Acts on all charges.

Compare the effect of loop size on induced current.

Smaller loop: Smaller induced current. Larger loop: Larger induced current.

Compare the effect of loop orientation on induced current.

Loop parallel to B: Minimal induced current. Loop perpendicular to B: Maximum induced current.

Define magnetic force.

The force exerted on a moving charge or current-carrying conductor in a magnetic field.

What is induced current?

Current generated in a conductor due to a changing magnetic field.

Define magnetic flux.

A measure of the quantity of magnetism, being the number of magnetic field lines passing through a surface.

What is the meaning of dl⃗\vec{dl}dl in the formula for magnetic force?

dl⃗\vec{dl}dl is the infinitesimal displacement vector of the conductor.

Define the term 'external magnetic field'.

A magnetic field originating from a source outside the conducting loop being considered.
