Direction of Magnetic Field

A current carrying loop is placed in the non-uniform magnetic field whose variation in space is shown in fig. Direction of magnetic field is into the plane of paper. The magnetic force experienced by the loop is

A circular coil is in y-z plane with centre at origin. The coil is carrying a constant current. Assuming direction of magnetic field at x = – 25 cm to be positive direction of magnetic field, which of the following graphs shows variation of magnetic field along x-axis

State right hand thumb rule to determine the direction of magnetic field around a current carrying conductor. Apply this rule to find the direction of magnetic field inside and outside a circular loop of wire lying in the plane of a table and current is flowing through it clockwise .

A beam of protons enters a uniform magnetic field of 0.3T with velocity of 4xx10^5m//s in a direction making an angle of 60^(@) with the direction of magnetic field. The path of motion of the particle will be

A positively-charged particle (alpha particle) projected towards west is deflected towards north by a magnetic field. The direction of magnetic field is: (a) towards south (b) towards east (c) downward (d) upward

AB is a current-carrying conductor in the plane of the paper as shown in figure. What are the directions of magnetic fields produced by it at point P and Q? Given r_1gtr_2 , where will the strength of the magnetic field be larger?

An electron is moving along positive x-axis A unifrom electric field exists towards negative y-axis. What should be the direction of magnetic field of suitable magnitude so that net force of electrons is zero .

A bar magnet of magnetic moment M is hung by a thin cotton thread in a uniform magnetic field B. Work done by the external agent to rotate the bar magnet from stable equilibrium position to 120° with the direction of magnetic field is (consider change in angular speed is zero)

A bar magnet hung by a insulating thread In a uniform horizontal magnetic field and magnet is in equilibrium Initially. The torque required to keep the magnet at angle by 30° with the direction of magnetic field is t. Then the work done to rotate it by same angle from initial position is

With the help of a labelled circuit diagram, illustrate the pattern of field lines of the magnetic field around a current-carrying straight long conducting wire. How is the right hand thumb rule useful to find direction of magnetic field associated with a current-carrying conductor?
