In the application of magnets, Magnetic Flux (Φ) is an important index to measure the performance of magnets, especially in the fields of motors, audio speakers, and so on. So what is Magnetic Flux (Φ)? In this article, we will try to answer this question....
ICSE-MAGNETISM-Exercises (Section II) Short answer questions What are magnets and what do you mean by magnetism? 01:33 What are magnetic poles? 01:14 How will you show that magnetic force can pass through non-magnetic ma... 01:19 How can a magnet be prepared by the induction method?
is known as coercivity. the lack to retain the magnetic property of a substance is known as hysteresis. have you ever noticed that an iron nail which has been attached to a magnet for some time attracts other non-magnetic iron nails for a short span even after it has been detached from ...
What is the formula for induced EMF? The induced emf isε = - d/dt (BA cos θ). The magnitude of the magnetic field can change with time. The area enclosed by the loop can change with time. The angle between the magnetic field and the normal to the loop can change with time. ...
What is Intuition? True North Guidance An actual compass or magnetic navigational device doesn’t point to “true north” – it points north-ish. While a compass will point north, it doesn’t point to thegeographic North Pole, which is considered true north. Instead, a compass points to th...
A bar magnet is a rectangular piece of an object that shows permanent magnetic properties and are made from the ferromagnetic substance. Cylindrical and rectangular bar magnets are the types of bar magnet. They are used in educational institutes.
