The electromagnet meter costs much less.
The electromagnet meter need not be aligned with the earth’s magnetic field.
The permanent-magnet meter has a more sluggish coil.
The electromagnet meter is more rugged.
It increases meter sensitivity.
It makes a meter more physically rugged.
It allows for the measurement of a wide range of currents.
It prevents overheating of the meter.
