15 points!!:-) Need help ASAP! When does a compass NOT point towards magnetic north?

A. during a solar eclipse, which changes

Earth's magnetic field.

B. When there is another magnet close by.

C. When there is an unused battery close by.

D. When there is a coil of copper wire close by.

b i think so because it makes senes

When there is another magnet close by.

Explanation: The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet. ... When you take the compass away from the bar magnet, it again points north. So, we can conclude that the north end of a compass is attracted to the south end of a magnet.

i think it's 35 meters

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
