Magnetic force on a current

1. Electric force on current carrying wire.

2. Electric force on current carrying loop.

3. Magnetic moment  of a current carrying loop.

4. Magnetic force on current carrying loop.

5. Torque on current carrying loop.

Why torque is much better term then moment 

Why moment still exist in A-Level curriculum 

When two current loops attract or repel 

Why sin function 

Force on a current carrying loop in uniform magnetic field 

Internal magnetic pressure 

Force on a current carrying loop via magnetic moment 

Magnitude of the magnetic force on a straight current carrying wire  in uniform magnetic field 

F = (I*L ) x (B )        Right hand rule       Definition of Tesla unit 

Magnetic force between straight wires
