Option 3 : Increase in flux density

We know that, ϕ = BA

Where ϕ is the flux

B is flux density

A is the cross-sectional area

For the constant flux, B is inversely proportional to A.

So, by increasing flux density the area of the motor will get reduce and hence the size of the motor will get reduce.

Road damage is often down to a few factors such as the quantity of traffic, the weight of the vehicles passing on it, and environmental conditions. XYZ town has a port, called ABC. To get to ABC, there is a road, that is divided into two lanes. One for the traffic going towards ABC port, and the other for traffic going away from ABC port. The lane of the road that leads to ABC port, has significantly less damage, than the lane that leads away from it. Which of the following helps explain this best?
