The field of a circular loop around its axis is the magnetic field that is produced by a current flowing through the loop. It forms a pattern of concentric circles around the axis of the loop.
The direction of the field is determined by the right-hand rule. If you point your thumb in the direction of the current flow, then your fingers will wrap around the loop in the direction of the magnetic field.
Yes, the size of the loop does affect the strength of the field. The larger the loop, the stronger the magnetic field will be. This is because a larger loop can accommodate more current, resulting in a stronger magnetic field.
When the loop is tilted, the field lines become elliptical instead of circular. The strength of the field also decreases as the loop is tilted away from the perpendicular position. This is because the current is not flowing perpendicularly to the loop, reducing the overall strength of the field.
Yes, the field of a circular loop has several practical applications. It is commonly used in electromagnets, electric motors, and generators. It is also used in medical imaging machines such as MRI scanners and particle accelerators in scientific experiments.
