Q

Explain how the motor effect works?

A
  • When current is passed through a wire, it will produce a magnetic field
  • When placed inside another magnetic field, the two fields will interact, causing the wire to experience a force and move

Q

How to calculate force of motor effect?

A
  • Force (N) = magnetic flux density (T) x current (A) x length of wire (m)
