Question

A magnetic field with the same orientation as the Earth's field is said to
have:

A.reverse polarity
B. combined polarity
C. normal polarity
D. isochronal polarity

Answer 1

Answer: Normal polarity

Explanation:

Magnetic field in line with the earth field is said to have polarity.

If the magnetic field is in opposite direction with the earth's field, then, the polarity is said to be a reversed polarity.

But since the magnetic field is with the same orientation as the Earth's field, it is said to have normal polarity.
