Write the expression for the magnetic moment due to a planar square loop of side ‘l’ carrying a steady current I in a vector form.
In the given figure this loop is placed in a horizontal plane near a long straight conductor carrying a steady current I1 at a distance l as shown. Give reason to explain that the loop will experience a net force but no torque. Write the expression for this force acting on the loop.
a magnetic needle free to rotate in a vertical plane, orients itself vertically at a certain place on earth. what are the values of horizontal component of earth's mag field and angle of dip at that place?
A dip ciccle shows an apparent dip of 60 degree at a place where the true dip is 45 degree. if the dip circle is rotated throgh 90 degree, what apparent dip will it show? first of all please tell me what is the meaing of apparent dip.how can a dip be apparent? it should always be true dip?
an element delta l=delta x l is placed at the origin and carriersa current I=2A.find out magnetic field at point P on y axis at distance of 1.0m due to element delta x=1cm.give also direction of field produced?
why does a freely suspended magnet always points along north- south direction. ?
1) An electron and proton moving parallel to each other in the same direction with equal momentum enter into a uniform magnetic field which is at right angle to thier velocites trace their trajectories in the magnetic field.
A closely wound solenoid of 2000 turns and area of cross-section 1.6 × 10−4 m2, carrying a current of 4.0 A, is suspended through its centre allowing it to turn in a horizontal plane.
(a) What is the magnetic moment associated with the solenoid?
(b) What is the force and torque on the solenoid if a uniform horizontal magnetic field of 7.5 × 10−2 T is set up at an angle of 30º with the axis of the solenoid?
Horizontal component of earth's magnetic field at a place is root 3 times its vertical component . what is the value of angle of dip at the place ?
A ball of mass m is tied with two strings of equal length on a rod !!! If the rod is rotated with angular velocity w ( omega ) , then ------(1) T1 = T2........(2) T2 is more than T1......(3) T1 is more than T2.......(4) T1 = T2 / 6 ..............(NOTE ----- T1 AND T2 ARE THE TENSIONS OF STRING 1 AND 2 RESPECTIVELY !!! ) KINDLY HELP !!!
a coil of 40 ohm resistance, 100 turns and radius 6mm is connected to ammeter of resistance 160 ohm. coilis placed perpendicular to the magnetic field. when coil is taken out of the field 32 microcoulomb charge flows through it. the magnetic flux density is:
