Motor Effect

What is the name of the effect when the wire with current flowing through it is placed in a magnetic field and experiences a force?

How to figure out the direction of the force acting on the wire?

Why does the coil placed in the magnetic field spin?

• the current is in opposite direction on each side of the coil

• there is current flowing through the coil from positive terminal to the negative terminal

• there are two forces acting in opposite direction on each side of the coil

What happened after the coil rotate clockwise 180⁰?

What is added to the coil to change the direction of current in the coil every half-turn which makes the direction of the forces on each side of the coil remain the same so that the coil can rotate continuously and not keep flipping back and forth?

How to increase the speed of the rotation of the coil? (Choose more than one)

• Increase the current flow in the coil

• Increase the number of turns of the coil

• Reverse the current flow

• Use stronger magnet

• Reverse the North-pole and the South pole
