Magnetic field 1 of 8 What does the wire experience? a force on both left and right sides 2 of 8 Once loops is at 90 degrees? Rotation stops 3 of 8 What is a split-ring commutator? is split-metal ring that is connected to conducting brushes 4 of 8 Purpose of brushes? Allows electric current to pass onto the ring 5 of 8 Split ring commutator is used to? Switch the direction of current when the loop reaches 90' 6 of 8 What does the current produce? A turning force on the motor 7 of 8 Switching direction of current, split-ring commutator allows: Motor to keep rotating in same direction 8 of 8
