A current-carrying wire is positioned between the poles of a magnet. If the electric current in the wire flows in the direction shown, the force on the wire is out of the page. Three statements describing different conditions and the effect on the wire are given. 1. If the current is directed towards the top of the page and the magnetic field direction remains unchanged, the force produced acts into the page. 2. If the current is directed towards the bottom of the page and the magnetic field is reversed, the force produced acts into the page. 3. If the current in the wire is alternating, the wire vibrates into and out of the page. Which of these statements are correct?
- A1, 2 and 3
- B1 and 2 only
- C1 and 3 only
- D2 and 3 only
