The frictional force is in the opposite direction
The electrical energy consumed by a toaster is 0.033 Kwh.
<u>Explanation</u>:
The power utilized by the toaster is 400 W.

The toaster is operated for 5 Minutes.

We know that,

Substitute the values in the above formula to obtain electrical energy,

Electrical energy = 0.4 × 0.083
Electrical energy is 0.033 Kwh.
It is basically shielding a magnetic field. This can be done with rubber or any other material that is thick. Normally small magnets already block the shield.
