The horizontal component of earth 's magnetic field at a place is B and angle of dip is 60 degrees. What is the value of vertical component of earth 's magnetic field at equator?
This question was asked in 2012 boards.I asked ths question yesterday also and the answer given by you is different from that available on this site where question-answers of previous year board papers are given.
there the answer is given to be zero and i don't undestand how. please review the question and explain how the vertical component of earth's magnetic field is zero at equator.
thank you
if a magnet is suspended at an angle 30 degree to the magnetic meridian the dip needle makes angle of 45 degree with the horizontal. the real dip is ??
true value of dip at a place is 45 degree.the plane of the dip circle is turned through 60 degree from the magnetic meridian.find apparent value of dip?please explain me the question with the help of figure a and give its solution.
Two magnets of magnetic moments M and 31/2 M are joined to form a cross. The combination is suspended in a uniform magnetic field B. The magnetic moment M now makes an angle θ with the field direction. find the value of angle θ.
why a galvanometer is not used to measure current in a given circuit?
A wheel with 8 metallic spokes each 50cm long is rotated with a speed of 120rev./min . The earth's magnetic field at the place is 0.4G and the angle of dip is 60 . Calculate the emf induced between the axle and the rim of the wheel. How will the value of emf be affected if the number of spokes were increased ?
two identical charged particles moving with same speed enter a region of uniform magnetic field. if one of these enters normal to the feild direction and the other along a direction at 30'c with the field , what would be the ratio of their angular frequencies?
in what respect is a toroid different from a solenoid ? draw and compare the pattern of magnetic field lines in the 2 cases
Apparent dips when dip circle is placed in two mutually perpendicular directions are 30 and 45 degree.What is actual dip at that place???
A rod of length L, along East-West direction is dropped from a height H.
A charge Q moving in a straight line is accelerated by a potential difference V.it enter a uniform magnetic field B perpendicular to its path.Deduse in terms of B an expearence radius of circular path which is travels

A rod of length L, along East-West direction is dropped from a height H.
if B be the magnetic field due to earth at that place and angle of dip isx, then what is the magnitude of induced emf across two ends of the rodwhen the rod reaches the earth?A charge Q moving in a straight line is accelerated by a potential difference V.it enter a uniform magnetic field B perpendicular to its path.
