00:00again numerical 3 cm length of wire is moved at right angles across a uniform magnetic field
00:08with a speed of 2 meter per second if the current if the flux density
00:17is 0.5 tesla what is the magnitude of the induced emf
00:22so formula will be vpl sine theta v i.e. velocity b i.e. magnetic field 5 or l i
00:30.e. length
00:31and sine theta then sine 90 will be multiplied by multiplying the explanation
00:45after choose the correct statement
00:48so lance law is a statement of law of conservation of energy the lance law holds in a case of
00:55induced
00:55current so both and b dodo correct
01:03solway may correct statement transformer device which convert ac voltage of one magnet into another ac
01:11voltage of required magnitude will go say in transformer if the resistance of the coil is
01:17negligible then back emf is equal to applied voltage jv say transformer work on the principle of
01:26mutual induction you say
01:28and this answer is all of the above
01:32the self inductance is more in case of the iron core
01:49and then in order to convert galvanometer into voltmeter so we know very high resistance
01:55any d option
02:06according to ampere's law
02:10the sum of the current b al for all path element the crack loop to new note i
02:33when a current charged particle is projected
02:38perpendicular in magnetic field
02:40this is also very important
02:42so what answer is circular
02:44and relation between one tesla 10
02:47bar 4 boss
02:55if our diamagnetic substance is brought near
02:59north or south of pole
03:00bar magnet it is repelled by the pole
03:02means we can have a bit of a
03:08so on the front or pole
03:11current쉬
03:11is mines
03:12then the spring remain the same or induced current in a conductor can be increased strong magnetic
03:21field increase number of turns increase speed of loops they be all of the above-face cancer
03:30so explanation bhi rake liyate hai
03:33yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah��
03:41a related to the conductor is that you can see it simply so you know the magnetic flux the
03:53primary as secondary coil are around on soft iron
03:56and power.
03:59This is very high resistance.
04:03This is circular.
04:14Since the magnetic force is always perpendicular to the velocity of charge particle, the particle
04:21will under circular motion.
04:23If a magnetic is proud toward a dimagnetic material, dimagnetic atoms and molecule
04:31generator orbit electron current, the magnetic field associated with these orbital current
04:40will orient so that the dimagnetic substance will be repelled by the approaching magnetic
04:48lens of physics per practical this behavior.
04:53This is our explanation.
04:55This is the bill sine theta formula.
04:58This will remain the same reason.
05:02Each loop of a spring will have current in the same direction.
05:08Each loop will attract the adjacent forces and therefore the spring will weak response.
05:15Which means the
05:16wings are not necessary.
05:16The
