What is the effect of increasing the magnetic field strength?
Increases the induced current and magnetic force.
What happens if a conducting loop moves faster through a magnetic field?
Higher induced current and stronger magnetic force.
What is the effect of increasing the number of turns in a conducting loop?
Higher induced current due to increased magnetic flux.
What happens when the plane of the loop is perpendicular to the magnetic field lines?
Maximum induced current and force occur.
What happens when the direction of the current is reversed?
The direction of the magnetic force is reversed.
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.
