Where is the magnetic field of a bar magnet strongest?

1. Where is the magnetic field of a bar magnet strongest? a) Outside the magnet, near the north pole of the magnet. b) Outside the magnet, near the south pole of the magnet. c) Beside the magnet. d) Inside the magnet.

2. What does it mean to say that a bar magnet is pointing eastward? a) The bar magnet is aligned west to east with the west end being the south pole of the magnet and the east end being the north pole of the bar magnet. b) The bar magnet is aligned west to east with the west end being the north pole of the magnet and the east end being the south pole of the bar magnet. c) A bar magnet never points eastward. By definition, a bar magnet always points northward. d) None of the above.

3. A current flows northeastward in a horizontal wire in a downward directed magnetic field. What is the direction of the magnetic field due to the wire at a point that is at the same elevation of the wire and is southeast of the wire? f) Southeastwardg) Southwestwardh) Upwardi) Downwardj) None of the above. a) Northwardb) Southwardc) Eastwardd) Westwarde) Northeastward

What is the direction of the force, if any, on a positively charged particle that has a northward velocity and is just east of (and at the same elevation as) a straight horizontal wire which is carrying a northward current?
