is the frequency of some electromagnetic radiation somewhere.
Depending on the height of the building they can break due to impact on the floor.
Answer:
Current in the toroid will be 
Explanation:
We have given number of winding in rectangular toroid N = 1500
Self inductance of toroid L = 0.06 H
Magnetic energy stored in toroid 
We have to find the current in the toroid
Magnetic energy stored is equal to 


So current in the toroid will be 
Because it eats plants and animals.
