AB is a current carrying conductor in the plane of the paper as shown in figure.The direction of the magnetic field produced by it at point P isA out of the plane of paper at point P. B  parallel to the plane of paper at point P. C into the plane of paper at point P. D random.

Imagine a current carrying circular loop ofwire on the plane of your answer sheet. Themagnetic field inside the loop is into the planeof the paper.(i) What must be the direction of the currentin the loop?

wire parallel to the paper moves downward into a flux density directed into the paper. The induced current will be ... a) directed to the left b) directed to the right c) zero because the motion is parallel to the field d) opposite to the induced emf, according to Lenz's law.

A vertical wire carries a current in upward directon. If an electron beam sent horizontally towards the wire, then it will deflectedVertically downwards and perpendicular to the plane of the paperVertically upwards and perpendicular to the plane of the paperIn the plane of the paper No deflection

A current carrying closed loop in the form of a right angle isosceles triangle ABC is placed in a uniform magnetic field acting along AB. If the magnetic force on the arm BC is Fthe force on the arm AC is A testbook B C

The direction of the magnetic field lines produced when a current is passed through a conducting wire, from the conductor isA perpendicular, outside B perpendicular, inside C parallel D circular around it
