Unlike a magnet's effect on metals and other magnets, magnetic fields don't attract or repel ions, but they can deflect ions under certain conditions. The ions must not only be moving, they must move on a path perpendicular to the magnetic field.

Basics of Magnetism. ... A magnet is an object that exhibits a strong magnetic field and will attract materials like iron to it. Magnets have two poles, called the north (N) and south (S) poles. Two magnets will be attracted by their opposite poles, and each will repel the like pole of the other magnet.

Magnetic field is non conservative in general, but in the special case of no currents and no time varying electric fields, it will act as a conservative field. NOTE: Any field with a curl will, in general, be non-conservative and magnetic field, indeed, has a curl (from Maxwell's laws of electromagnetism).

Answer: Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density.

Magnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre.

Similarities between magnetic fields and electric fields: ... Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract. Electric field points in the direction of the force experienced by a positive charge ...

the magnetic field must be inhomogeneous because the magnetic force is proportional to the gradient of the field. ... In fact, in elementary courses of electromagnetism it is very easily shown that if the magnetic field is uniform (i.e., homogeneous field), the force on a magnetic moment is zero.

Characteristics Of Electromagnetic Waves An accelerated charge produces a time-varying magnetic field which in turn produces a time-varying electric field. Thus, electromagnetic wave consists of sinusoidal time-varying electric and magnetic fields and both the fields are perpendicular to each other.

Properties. The physical and chemical properties of magnetic nanoparticles largely depend on the synthesis method and chemical structure. In most cases, the particles range from 1 to 100 nm in size and may display superparamagnetism.

Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.
