Answer:
The intensity of the light from the bulb would be
3.501 x 
W/
Explanation:
Given
The Power = 110 n W = 110 x 
W
the distance r = 50 mm = 50 /1000 = 0.05 m
The intensity can be obtained with the relationship below;
I = Power/area ......1
The area of the sphere would be used in this case since the bulb is spherical; A=4π
Putting it into equation 1, we have;
I = P/ 4π
I = 110 x / 4 x π x 
I = 3.501 x W/
Therefore the intensity of the light from the bulb would be
3.501 x W/
When an electric current is flowing through a wire, there is a magnetic <em>field</em> produced. The lines of magnetic force are circles around the wire.

Answer:
Magnetic field is the strength of magnetism created by a magnet, whereas the magnetic force is the force due to two magnetic objects. The concepts of magnetic field and magnetic force are widely used in fields such as classical mechanics, electromagnetic theory, field theory and various other applications.
