Whenever an electric current passes through it, a magnetic field is created. As previously stated, the power of the magnetic field depends on the electric current. Therefore, by varying the current as per our need, we can easily magnetize and demagnetize the electromagnet, enabling us to control...
The presented configurations include an electromagnet with a fast switching rate (fast field-cycling relaxometer), a permanent magnet with a strong magnetic field gradient, and a permanent magnet where the sample is placed in a homogeneous field. Measurements of a series of liquid samples that can...
The previous chapter explored the fundamental differences between solenoid and toroid cores. By examining these concepts further, we can identify the benefits and limitations of each design. Below are the advantages and disadvantages of toroidal transformers compared to other types of transformers. Advant...
