The direction of the magnetic field in front of the wire closest to the student is on the left. The direction is found by the right-hand rule.
<h3>What is the right-hand rule?</h3>
The right-hand rule is a popular mnemonic for remembering how axes in three-dimensional space are oriented.
The fact that the three axes of three-dimensional space have two different orientations gives birth to the majority of the many left-hand and right-hand rules.
Using the right-hand rule, we can recall this diagram. Your thumb points in the direction of the magnetic force pushing on the moving charge
If you point your pointer finger in the direction of the positive charge and then your middle finger in the direction of the magnetic field.
