In 1820, Hans Christian Oersted (1777-1851) proved electric current can affect a compass needle. However,Oersted could not explain why.

Electric current causes magnetic field around conductor by producing a moving electric charges and the intrinsic magnetic moments of an elementary particles that is associated with a fundamental quantum property.
Increase the magnitude of the electric current.
Moving charges produce magnetic fields.Answer 2In other words, when the charge moves along a conductor it creates an electric current. The current induces a magnetic field around the conductor.
Well when an electric current flows through a conductor a magnetic field is produced. And a changing magnetic flux through a conductor produces a current in the conductor.
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.

The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.

A electric current produces a magnetic field
The magnetic field or energy associated with the magnetic field will no longer be generated if the current is turned off.
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
The Magnetic field itself can do no work and is a byproduct of the electric current. The energy is stored in the current or provided by whatever drives the current.
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
that is a magnetic field
