The magnetic field lines near a long straight wire carrying current is the magnetic field near a long straight wire is concentric circles.
The magnetic field is the place around a magnetic fabric or a moving electric-powered price within which the pressure of magnetism acts. A pictorial illustration of the magnetic discipline describes how a magnetic force is shipped inside and around a magnetic material.
A magnetic field is a vector area that describes the magnetic impact on shifting electric fees, electric-powered currents, and magnetic substances. A moving charge in a magnetic subject experiences a pressure perpendicular to its very own pace and to the magnetic field.
Examples of magnetic fields are a compass, a motor, the magnets that keep stuff on the fridge, train tracks, and new curler coasters. All moving prices supply upward push to a magnetic area and the fees that flow thru its areas, experience a force.
