A visco-elastic material is one with both the properties of a liquid and the properties of an elastic solid. The combination of these two types of properties is excellent when it comes to absorbing or spreading energy because these two types of materials deal with energy in different ways.
Electric and magnetic fields (EMF) are invisible lines of force that surround any electrical device. Electrical wiring, electrical equipment and power lines all produce electric and magnetic fields. Electrical fields and magnetic fields can be characterized by their wavelength, frequency and amplitude (strength).
Well, technically it is not measured in volts. The strength of an electromagnet depends on the electrical current which flows through its wires, but â¦ not on what drives that current. The current is measured in the amount of charge per unit time that flows through the wires.But when it comes to measuring the magnet, you have to refer to the magnetic field.he strength of an electromagnet depends on the electrical current which flows through its wires, but â¦ not on what drives that current. The current is measured in the amount of charge per unit time that flows through the wires.
