Determine whether the following statement is true or false: When a bar magnet is placed in the Earth's magnetic field with its north pole pointing towards geographic North, the neutral points formed by the mutual cancellation of the magnet's field and the Earth's horizontal field lie along the magnet's equatorial line (broadside-on position).
Cevap: Cevap
Cevap
True. When a bar magnet has its north pole pointing North, the magnetic field along its equatorial (broadside-on) line points South, opposing the Earth's horizontal magnetic field to create neutral points.
The statement is correct because neutral points are formed at positions where the external magnetic field of a magnet is equal in magnitude and opposite in direction to the Earth's horizontal magnetic field component (). When the north pole of a bar magnet points North, its field along the broadside-on (equatorial) axis is directed South (opposite to ), leading to field cancellation and the creation of two neutral points on that axis.
