What are the steps to calculate magnetic force on a conductor?

  1. Determine the induced current (I) in the conductor. 2. Identify the magnetic field vector (B⃗\vec{B}B). 3. Define the displacement vector (d⃗\vec{d}d). 4. Integrate I(d⃗×B⃗)I(\vec{d} \times \vec{B})I(d×B) over the length of the conductor to find the magnetic force F⃗B\vec{F}_{B}FB​.

What are the steps to apply Newton's Second Law to a conducting loop in a magnetic field?

  1. Identify all forces acting on the loop (including magnetic force). 2. Calculate the net force (F⃗net\vec{F}_{net}Fnet​). 3. Use F⃗net=ma⃗\vec{F}_{net} = m\vec{a}Fnet​=ma to find the acceleration (a⃗\vec{a}a). 4. Use kinematic equations to predict the loop's motion.

What are the differences between translational and rotational acceleration caused by magnetic forces?

Translational Acceleration: Results in linear motion, changes the object's position in a straight line. | Rotational Acceleration: Results in rotational motion, changes the object's angular velocity around an axis.

Define magnetic force vector (F⃗B\vec{F}_{B}FB​).

The vector representing the force exerted on a current-carrying conductor by a magnetic field.

Define induced current (III).

The electric current generated in a conductive loop due to a changing magnetic flux.

Define displacement vector (d⃗\vec{d}d).

A tiny vector representing a small segment of the conductor's length, used in calculating magnetic force.

Define magnetic field vector (B⃗\vec{B}B).

A vector field that describes the magnetic influence of electric currents and magnetic materials.

Define magnetic flux.

A measure of the amount of magnetic field lines passing through a given area. It's the product of the magnetic field strength and the area perpendicular to the field.

Define translational acceleration.

Acceleration in a straight line, resulting in a change in linear velocity.

Define rotational acceleration.

Acceleration around an axis, resulting in a change in angular velocity.
