Question 2 - Assertion Reasoning questions (MCQ) - Chapter 13 Class 10 - Magnetic Effects of Electric Current

Assertion (A): In Fleming’s Left Hand Rule, the direction of magnetic field, force and current are mutually perpendicular.

Reason (R): Fleming’s Left hand Rule is applied to measure the induced current.

Answer:

Fleming's left hand rule is used to find the direction of the force/ motion of a conductor.

Fleming's right-hand rule states that if we hold the forefinger, the middle finger and the thumb of our right hand at right angles to one another such that

• Forefinger points in the direction of magnetic field
• Thumb in the direction of the motion of conductor
• Then the direction which the middle finger points gives the direction of the induced current.

Thus,

• Assertion is true.
• Reason is false.

So, the correct answer is (c)
