1. Answer all parts of the following question.

a. Having no magnetic fields around and a sensitive compass that can detect the

Earth’s magnetic field, geographically, where would the needle be pointing to? (imagine

being in the middle of the ocean without any electronics and seeking some help with

directions)

b. What of these factors affect the magnetic field produced by a thin circular coil? (choose all that applies)

i. The resistance of the circuit.

ii. The radius of the coil.

iii. The air pressure around the coil.

iiii. The number of turns that makes up the coil

Solutions

Expert Solution

a.A sensitive compass points north because all magnets have two poles , a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet.A magnetic compass points to the earth's magnetic poles, which are not the same as earth's geographic poles. Furthermore, the magnetic pole near earth's geographic north pole is actually the south magnetic pole. When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.

b. ii and iiii

Explanation:-The strength of magnetic field depends upon:

(ii) Magnetic field(B) is inversely proportional to the radius of the coil.

(iiii) B is directly proportional to the number of turns n of the coil. For each circular turn, the direction of current is same. So, the fields due to the various turns get added up.
