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 \(\vec{dl}\) in the formula for magnetic force?
\(\vec{dl}\) 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.
Steps to determine magnetic force direction using the right-hand rule?
1. Point thumb in current direction. 2. Fingers in magnetic field direction. 3. Palm shows force direction.
Steps to calculate the net force on a conducting loop in a magnetic field?
1. Calculate the magnetic force. 2. Identify other external forces. 3. Sum all forces to find the net force.
Steps to predict motion of a conducting loop using Newton's Second Law?
1. Calculate net force. 2. Determine acceleration using \(\vec{a} = \frac{\vec{F}_{net}}{m}\). 3. Use kinematics equations.
Steps to calculate induced emf in a loop with changing magnetic flux?
1. Calculate magnetic flux \(\Phi\). 2. Apply Faraday's Law: \(\epsilon = -\frac{d\Phi}{dt}\).
Steps to determine the magnetic force on a current-carrying wire?
1. Determine the current I. 2. Find the magnetic field B. 3. Use \(\vec{F}_{B}=\int I(\vec{dl} \times \vec{B})\) to calculate the force.
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.
