Answer:
Yes.
Explanation:
The strength of the magnetic field is the magnetic field intensity .
The magnetic field intensity is defined as (B) = FLUX/AREA.
Hence, the magnetic flux density increases as the area of the coil decreases .
The magnetic field intensity is directly proportional to the magnetic field flux density, and the radius of the coil is directly proportional to its area.
Hence, as the radius of the coil increases both the magnetic field intensity and the magnetic flux density decreases, and vice versa. Hence, the strength of the magnetic field is indirectly proportional to the radius of the coil.
