Question

conduct an experiment and collect data to determine the effect of changing the strength of the bar magnet on the strength (magnitude) of the magnetic field. how does increasing the strength of the bar magnet affect the strength (magnitude) of the magnetic field? it increases. it is not affected. it decreases.

Explanation:

The magnetic field strength around a bar - magnet is directly related to the strength of the bar - magnet. A stronger bar - magnet will produce a stronger magnetic field.

Answer:

It increases.
