A magnet oscillating in a horizontal plane has a time period 3 seconds at a place where the angle of dip is 30 degree and 4 seconds at another place where the angle of dip is 60 degree compare the resultant magnetic field at two places.
Hello,
The time period of oscillation of a magnetic needle in earth’s magnetic field is given by,
Let B1 & B2 be the earth’s magnetic field at the locations.
Hope this helps,
Keep posting and have a nice day!
