Solenoids: Working Principle,
Types & Applications

Comments Off on Solenoids: Working Principle,
Types & Applications

A solenoid is a variety of electromagnet consisting of a copper wire coil wound tightly into a helix, an iron or steel housing, and a mobile plunger made of magnetic material. When an electric current passes through the coil, the solenoid produces a magnetic field and converts that magnetic energy into mechanical motion. Essentially, a […]

A Guide to Magnetic Particle Imaging (MPI)

Comments Off on A Guide to Magnetic Particle Imaging (MPI)

Medical professionals rely on access to high-quality preclinical imaging tools to monitor healthy and diseased tissue, make diagnoses, and develop treatment plans. Three tomographic preclinical imaging options have been available over the last few decades: positron-emission tomography (PET), computed tomography (CT), and magnetic resonance imaging (MRI). Each has its own drawbacks, from using ionizing radiation […]

Electromagnets in the Aerospace
Industry: Thrusters

Comments Off on Electromagnets in the Aerospace
Industry: Thrusters

Electromagnetic propulsion (EMP) requires two primary components: an electromagnet to generate the magnetic field and a propulsion component. EMP uses a current from the magnetic field to accelerate the object. Through Lorenz Force, the electrified conductor encounters a force in a perpendicular direction to the magnetic field and the current. If a liquid or gas […]

Vacuum Casting

Comments Off on Vacuum Casting

Vacuum casting of wire coils removes air from the material surrounding the windings, which results in better thermal control of the component. This process also creates specific physical geometries that enhance the structural integrity of coils and allow for better compliance with space requirements. Vacuum casting is an effective process to protect coils from humidity […]
