To solve the problem step by step, we will follow the concepts of magnetic pole strength and the force between them.Step 1: Understand the Problem We have two magnetic poles, where one pole (P1) is four times stronger than the
40 The diagram shows a coil of wire between two poles of a horse shoe magnet. When the coil is rotated, a potential difference across the lamp is produced. The. lamp is connected in series with a semiconductor diode.Rotation一5N Slip rings Carbon brushes Viamp Which of the following best...
- Since liquid oxygen is paramagnetic, it will be attracted to the magnetic poles and can remain suspended between them. Therefore, the correct answer is C) Paramagnetic. 6. Conclusion: Liquid oxygen remains suspended between the two pole faces of a magnet because it is a paramagnetic substance...
