The electromagnet makes use of an iron core situated in a solenoid through which electric current is passed. This current creates a magnetic field at the center of the solenoid that orients the magnetic moments in the domains of the iron core, which in turn results in a significant ...
Measure: Given a container graduated in cubic centimeters, the student could be asked to measure a specific amount of liquid. Name:The student could be asked to name the parts of an electromagnet. Order:The student could be asked to order a number of animal life forms according to their nor...
Principle of Analytical Balance Analytical balance calculates weights based on the force required to balance the mass of a sample rather than utilizing actual masses. They produce a force to balance the sample using an electromagnet, then output the result by measuring the force required. A transpar...
A stir bar and a hot plate stirrer are the two main parts of a magnetic stirrer. A stationary electromagnet,a hot plate, a temperature control knob, and a speed control knob are some of the additional components found inside a hot plate stirrer machine. ...
terminal. The movement of electrons in a copper wire or other conductive material also generates a magnetic field that has a direction and magnitude determined by the electric current direction and hence the movement of electrons; this is the principle upon which an electromagnet is...
Physics. (of an electric current) produced by induction: As a coil on a pendulum passes between the poles of an electromagnet, the induced current causes the small bulb to light up. Genetics. (of a gene) having increased expression as a result of the inactivation of a negative control syst...
