Question

the bar magnet is oscillating in a magnetic field and frequency is 10Hz. If another identical piece of braze is placed over the magnet. The frequency of the combination in the field is?​

Answer 1

The frequency of the combination in the field will be 7.07 Hz

Explanation:

The frequency of the magnet bar is given by:

f = 1/2π √(B/I)     ………. (i)

Equation (i) shows that the frequency of field is inversely proportional to inertia of the bar magnet. So, if the identical braze is placed over the magnet, then frequency will decrease by factor 1/√2. Hence,

Frequency of the combination in the field =(1/√2) × 10 = 7.07 Hz  

Answer 2

Answer:

I think it's 10/root2
