Question

Horatio drew a diagram to illustrate how magnetism is produced by electric currents

Answer 1

Answer:

B)The magnetic field does not continually spread outward from the wire.

Explanation:

The lines of the magnetic field produced by an electrical current passing through a wire are concentric circles around the wire. The intensity of the magnetic field decreases as the inverse of the distance from the wire, $\frac{1}{r}$.

Therefore, the error in the figure is that the magnetic field lines do not spread out radially from the wire, but they should be concentric circles around the wire itself.

Answer 2

The magnetic field does not continually spread outward from the wire.
