TS EAMCET · Physics · Magnetic Effects of Current
At a certain place, a magnet makes 30 oscillations per minute. At another place where the magnetic field is doubled, its time period will be
- A \(\sqrt{2} \mathrm{~s}\)
- B \(2 \mathrm{~s}\)
- C \(4 \mathrm{~s}\)
- D \(1 / 2 \mathrm{~s}\)
Answer & Solution
Correct Answer
(A) \(\sqrt{2} \mathrm{~s}\)
Step-by-step Solution
Detailed explanation
Time period of magnet in magnetic field \[ T \propto \frac{1}{\sqrt{B}} \] If magnetic field is doubled, then…
