Neutral Points in a Magnetic Field
As a result of two magnetic fields acting at the same place, the resultant field has a special feature. At a particular point, if the compass needle does not point in any particular direction, then there is no net magn..

If a small compass needle is placed at a point near the north pole of a bar magnet, the needle turns round on its pivot and settles in a fixed direction as shown in figure. At other points away from the pole the needle settles tangent to the field lines shown. The magnet..

A magnetic field is defined as a region in which a magnetic force is present. In a magnetic field, the magnetic dipole (two equal and oppositely charged or magnetized poles separated by a distance) experiences a turning..
Torque on a Bar Magnet in a Uniform Magnetic Field
The behavior of a bar magnet in a uniform magnetic field is similar to that of electric dipole in a uniform electric field. The above figure. Let 2l be the magnetic length of a magnet and m be the strength of each pole. ..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
