Question

which diagram correctly represents the direction of the magnetic field around a bar magnet?
which of the following describes an object that must have a net negative charge?
it contains more molecules than atoms.
it contains more electrons than protons.
it is carrying an electric current.
it is made of metal.

Explanation:

• For question 2: The magnetic field lines around a bar magnet go from the north pole to the south pole outside the magnet.
• For question 3: An object has a net negative charge when it has more electrons (negative - charged particles) than protons (positive - charged particles).

Answer:

• Question 2: The first diagram (assuming the first diagram has field lines going from N to S outside the magnet).
• Question 3: It contains more electrons than protons.
