1. Point thumb in the direction of the current (I). 2. Point fingers in the direction of the magnetic field (B). 3. Palm points in the direction of the force (F).

1. Point thumb in the direction of the current (I). 2. Curl fingers; the direction of the curl indicates the direction of the magnetic field (B).

1. Determine the forces on each side of the loop using $\vec{F} = I \vec{L} \times \vec{B}$. 2. Calculate the torque produced by these forces. 3. Use $\tau = NIAB \sin(\theta)$ to find the total torque, where N is the number of turns, A is the area, and $\theta$ is the angle between the normal to the loop and the magnetic field.

1. Use RHCR to find the magnetic field created by one wire at the location of the other. 2. Use RHR to find the force on the second wire due to the magnetic field from the first wire. 3. Determine if the wires attract (parallel currents) or repel (anti-parallel currents).

Use the Right-Hand Curl Rule (RHCR). Point your thumb in the direction of the current, and your fingers will curl in the direction of the magnetic field.

N: number of turns in the loop, I: current in the loop, A: area of the loop, B: magnetic field strength, θ: angle between the normal to the loop and the magnetic field.

Thumb: Direction of the current (I), Fingers: Direction of the magnetic field (B), Palm: Direction of the force (F).

Increasing the current increases the strength of the magnetic field around the wire.

The loop experiences a torque that causes it to rotate, aligning its magnetic moment with the external field.

The magnetic force on the wire is zero.

The magnetic force on the wire is maximum.

The wires attract each other.

The wires repel each other.
