00:00Heating our magnet will, this answer will be weak in it.
00:05To enhance magnetic flux, primary and secondary coils are
00:12This type of soft iron core
00:15Now the rest of the numericals are
00:18Now let's check in the explanation of these all
00:30What is the solution?
00:33This is the whole explanation
00:38Magnetism occurs when atoms in magnetic metals are lined up in the same direction
00:43Forming poles when you heat the magnet you add energy
00:49This causes some of the atoms to vibrate until they go out of alignment
00:55The fever atoms that are aligned the less strength the magnetically
01:00This is the soft iron core which is about 50,000 more dense
01:05This is the energy formula
01:09Energy is equal to half li square
01:13L means inductance
01:14I means current
01:17Induce EMF
01:18This formula we have done
01:23EMF
01:24What we have done
01:24L
01:24Delta
01:25I upon delta
01:27Then voltage of primary into current of primary is equal to voltage of secondary current of secondary
01:40Here
01:41Here
01:41Number of secondary
01:44Upon number of primary
01:45The ratio is 3 to 2
01:47Voltage of primary is 30
01:50Voltage of secondary is 30
02:01Voltage of secondary is 30
02:02Equal to VBL
02:04VBL
02:04Sin
02:05Theta
02:08Induce EMF
02:12And del phi upon del t
02:14At this one
02:15For say 50
02:15A
