Practice Electromagnetic forces and induction with authentic MYP MYP Physics exam questions for both SL and HL students. This question bank mirrors Paper 1, 2, 3 structure, covering key topics like mechanics, thermodynamics, and waves. Get instant solutions, detailed explanations, and build exam confidence with questions in the style of MYP examiners.
True or False: In electromagnetic induction, the direction of the induced current changes instantly if the direction of motion of the magnet relative to the coil is reversed.
True or False: In a simple DC motor, reversing the direction of the magnetic field while keeping the current direction the same will cause the coil to rotate in the opposite direction.
Consider the following conditions for a conducting coil: I. There is relative motion between the coil and a magnet. II. The magnetic field strength through the coil changes.
In which of these situations is an electromotive force (emf) induced in the coil?
Pushing the north pole of a magnet into a coil at induces a current of in the coil. The south pole of the same magnet is then pulled out of the same coil at .
What is the current induced in the coil during this second action?
When modeling induction as 'cutting through magnetic field lines,' which of the following would NOT increase the number of lines cut per second?
For an ideal gas-law style calculation in induction, we model 'stronger' magnetic fields by representing the field lines as:
Which of the following conditions is necessary to induce an electric current in a closed loop of wire using a stationary magnet?
Which of the following describes the magnetic field conditions on the side of a current-carrying wire towards which the magnetic force is directed?
A wire carrying an electric current is placed in a magnetic field. Into which form of energy is the electrical energy supplied to the wire primarily converted?
If the current flowing through a wire in a fixed magnetic field is tripled, how does the force on the wire change?
