IIT JEE : Magnetic Effect Of Current And Magnetism QUESTIONS AND ANSWERS :: part1 : 26 to 30

Following IIT JEE Entrance Multiple choice objective type questions and answers will help you in Maths, Physics and Chemistry 2024 examinations :

26.A long wire carries a current of 20 A along the axis of a solenoid, the field due to the solenoid is 4 mT. The resultant field at a point 3 mm from the solenoid axis is:

1.33 mT
4.2 mT
2.1 mT
8.4 mT

27.A conducting loop carrying a current is placed in a non-uniform magnetic field perpendicular to the plane of loop. Then:

loop must experience force
loop may experience torque
loop must experience torque
none of the above

28.A uniform electric field and a uniform magnetic field are acting along the same direction in a certain region. If an electron is projected along the direction of the fields with a certain velocity, then:

its velocity will decrease
its velocity will increase
it will turn towards right of directions of motion
it will turn towards left of direction of motion

29.The direction of magnetic field at a point due to an infinitely long wire carrying current is:

parallel to the current
antiparallel to the current
along the perpendicular drawn from a point on the wire
perpendicular to the plane containing the conductor and the point
