Question

When testing one bar's middle point near the end of another bar, what does little or no pull indicate?

पर्याय

• A single magnetic pole has been isolated.

• The bar being tested is plain iron; its midpoint/equatorial region is a pole.

• Both bars are magnets because attraction alone confirms magnetism.

• The bar being tested is the magnet; its midpoint/equatorial region has a weak field.

Answer 1

Little or no pull is associated with the magnet's midpoint/equatorial region, where the field is weak. That observation helps identify the bar being tested as the magnet.
