All Flashcards
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.
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 in the formula for magnetic force?
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.
