Respuesta :
The magnetic field direction produced by an electric current will change when the electric current direction changes.
What is a magnetic field?
It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.
The equation below helps us to understand the relation between the magnetic field and electric current.
[tex]I=-\frac{B}{R} \frac{d\phi}{dt}[/tex]
where,
E be the induced emf.
I will be the induced current.
B is the magnetic field.
