The magnetic fields of magnets are most powerful at the <u>poles of a magnet</u>. Without any difference in the magnitude, both the poles have equal amount of Magnetic field intensity at their poles.
If you see the field lines we can see the field lines start from the North Pole run parallel and end at the South Pole. The field lines are concentrated more at the poles hence the magnetic field intensity or the magnetic field itself is more at the poles than any other part.
The answer is : 35 to 52 minutes.
Hope this helps!

Sample Response: The technology being described is fiber optics. Since they are small and flexible, they enable doctors to see areas that they might otherwise be unable to see without surgery.
To maximize the power delivered to load, we should minimize the internal resistance which means option A is correct.
<h3>What is the relationship between the power and the internal resistance?</h3>
Power can be delivered to the internal resistance of a battery, but in a case whereby there is a decrease in the internal resistance will bring about the decrease in the lost power as well as the increase in the percentage of the power delivered to the device.
In this case, To maximize the power delivered to load, we should minimize the internal resistance
Therefore, Option A is correct.

A box residing on an inclined plane has following forces:
In the X- direction
Mg sin (theta) = horizontal component of weight of the box
f = Frictional force = uN , u = frictional factor, N= mg
In the Y- direction
upward force = Normal reaction of the box = mg
downward force = mg cos(theta) = vertical component of weight of the box
