Right Hand Grip Rule. Grip the wire with the right hand, with the thumb pointing along the direction of the current. The other fingers give the direction of the magnetic field around the wire.
The direction of the field lines shows how a compass would line up if placed at that point. We can use the right hand grip rule to remember the relationship between current and field around a wire
The ‘right-hand grip rule’ can be used to give the direction of the magnetic field lines produced by a current in a long straight wire
The right hand grip rule is a convention derived from the right-hand rule convention for vectors. When applying the rule to current in a straight wire for example, the direction of the magnetic field (counterclockwise instead of clockwise when viewed from the tip of the thumb)...
In mathematics and physics, the right-hand rule is a common mnemonic for understanding orientation conventions for vectors in three dimensions. Most of the various left- and right-hand rules arise from the fact that the three axes of 3-dimensional space have two possible orientations.
Electromagnetic Induction. Fleming's Right Hand Rule.
The magnetic field is strongest at its poles. The field around a magnet can be represented by lines with arrows on them.

The density of the induced magnetic field is directly proportional to the magnitude of the current. Direction of the circular magnetic field lines can be given by Maxwell's right hand grip rule or Right handed cork screw rule.
To represent the field around a magnet we use a diagram which needs to obey some rules (or conventions) so that whoever uses it can interpret it correctly.
