Question

Crowded field lines represent .......... magnetic field

Answer 1

1. Magnetic Field Lines are hypothetical lines that the North Magnetic Pole would move along if it could.
2. The magnetic field lines are crowded at the pole, where the magnetic field is strong, and are far apart towards the magnet's midsection and further away, when the magnetic field is weak.

Hence, Crowded field lines represent Stronger magnetic field.
