Magnetic Effect of Current Formulae For NEET

When current is passed through the conductor it will produce a magnetic effect around it, so basically the wire acts like a magnet, and it will interact with the permanent magnet you have placed next to it, this effect can be reversed by changing the direction of the current, which according to the rule changes the direction of the magnetic field produced by it.
