NEET 2024 Physics Magnetic Materials Multiple Correct Question
Type: Multiple Correct-conceptual-Hard-Class 12
A sheet is placed on a horizontal surface in front of a strong magnetic pole. A force is needed to :
A. hold the sheet there if it is magnetic.
B. hold the sheet there if it is non-magnetic.
C. move the sheet away from the pole with uniform velocity if it is conducting.
D. move the sheet away from the pole with uniform velocity if it is both, non-conducting and non-polar.
Choose the correct statement(s) from the options given below:
A
A, C and D only
B
C only
C
B and D only
D
A and C only
Correct Answer
Option D
Detailed Explanation
A magnetic sheet will be attracted to the pole, requiring force to hold it. A conducting sheet will experience eddy currents, requiring force to move it away. A non-conducting, non-polar sheet will not be affected.
