Can a magnetic field be negative
WebThe magnetic flux is a scalar quantity or dot product, and a positive or negative sign elucidates the positioning of the magnetic field. For an object in a uniform and non-uniform magnetic field, exterior flux is considered positive, and interior flux is assumed to be negative. The magnetic field can or cannot be zero if the magnetic flux ƟB=0. WebElectric and magnetic fields together are referred to as electromagnetic fields, or EMFs. The electric and magnetic forces in EMFs are caused by electromagnetic radiation. There are two main categories of EMFs: Higher-frequency EMFs, which include x-rays and gamma rays. These EMFs are in the ionizing radiation part of the electromagnetic ...
