What type of magnetic pole is the top pole face

Reference no: EM13294720

The force on a long wire is a maximum of 6.20 10-2 N when placed between the pole faces of a magnet. The current flows horizontally toward the observer and the magnetic field is vertical. The wire tends to move to the right when the current is turned on.

(a) What type of magnetic pole is the top pole face? North pole or South pole

(b) If the pole faces have a diameter of 11 cm and the magnitude of the magnetic field is 140 mT, estimate the wire current. (Hint: you can use the diameter as the length of the part of the wire in the field when estimate.) A
