increase

decrease

remain unchanged

either increase or decrease

Text Solution

Verified by Experts

The correct Answer is:

For a tangent galvanometer
`B=B_(H) tan theta`
Here `B=(mu_(0))/(4pi)(2pini)/(a) rarr (mu_(0))/(4pi)(2pini)/(q)=B_(H) tan theta`
or
`therefore` if the number of turns in the coil are doiubled the defelcytion will increase
