This is incorrect. Your expression in the region R > F is missing a denominator. Anyway, since your expression has (i2-i1), put your thumb in the direction of i1 and do the right hand rule thing. Ultimately, the direction the B-field will depend on which of the two currents is greater than the other. If your are given that i2 > i1, then the direction will be as you have chosen, else it will be the opposite direction.Tomi Kolawole said:
The right hand rule is a way to determine the direction of a magnetic field around a current-carrying wire or a magnet. It states that if you point your thumb in the direction of the current or the south pole of a magnet, then the direction your fingers curl around the wire or magnet represents the direction of the magnetic field.
To use the right hand rule for a solenoid, you must first determine the direction of the current flowing through the coils. Then, wrap your right hand around the solenoid in the direction of the current, with your fingers pointing in the direction of the magnetic field.
Yes, the right hand rule can be used for any type of magnet, including bar magnets, horseshoe magnets, and electromagnets. It can also be used for determining the direction of the magnetic field around a current-carrying wire or a solenoid.
Yes, the right hand rule is always accurate in determining the direction of a magnetic field. However, it is important to note that the direction of the magnetic field can change depending on the orientation of the wire or magnet, so the right hand rule must be used consistently.
The right hand rule and the right hand grip rule are essentially the same concept, with the only difference being the direction of the thumb. In the right hand rule, the thumb points in the direction of the current or south pole of the magnet, while in the right hand grip rule, the thumb points in the direction of the magnetic field. Both rules can be used interchangeably to determine the direction of a magnetic field.
