Question

Use the direction key at right to indicate the direction of the magnetic field at point P in each situation. Write the letter corresponding to your answer in the space provided. mro page m=(B=0) O Our of page I (in) . I (out)

Answer 1

a)

Always the magnetic field lines pass from North pole to south pole outside the magnet and inside the magnet from south to north. Now at the point P all the magnetic field will converge at into the south pole. Therefore they magnetic field lines shows the downward direction. So, answer is (c)

b)

The magnetic field lines will be in the upward direction at point P.So the answer is (g)

c)

From the right hand thumb rule we can say magnetic field lines will be into the page .So the answer is (j)

d)

From the right hand thumb rule we can say magnetic field lines will be in the direction of e .So the answer is (e)

e)

From the right hand thumb rule we can say magnetic field lines will be in the direction of f .So the answer is (f)
