Question
Indicate true or false in the following statements:
A) An Amperian loop must be outside a conductor.
B) Placing loops of wire on top of each other, in which the electric current flows in the same direction, produces a larger magnetic field than they each produce individually.
C) A moving electron does not generate a magnetic field.
D) A loop of electric current produces a magnetic field at the center of the loop parallel to the plane in which the current flows.
E) Two wires carrying current in the same direction attract each other.
Explanation / Answer
A) FALSE - you can assume amperian loop inside the conductor as well in order to calculate magnetic field.
B) TRUE - All the fields get added and net field is stronger than individual.
C) FALSE - Moving e is another form of current. All currents produce magnetic field.
D) FALSE - The magnetic field is perpendicular to the plane of current.
E) TRUE - similar currents attract. opposites repel. - opposite to charges.
