Overview of Electromagnets

            The laboratory electromagnets are mainly used for magnetic hysteresis research, magnetization coefficient measurement, Hall effect research, CI optical experiment, magnetic field annealing, nuclear magnetic resonance, electronic paramagnetic resonance, biological research, magnetic measurement, magnetic material orientation, magnetic product magnetization, etc.

            The experimental electromagnets independently developed by the company are mainly used for research on magnetic hysteresis, magnetization coefficient measurement, Hall effect research, magneto-optical experiment, magnetic field annealing, nuclear magnetic resonance, electronic paramagnetic resonance, biological research, magnetic measurement, magnetic material orientation, magnetic product magnetization and other research.

1. Dual adjustable variable air gap electromagnet iron can improve the size and uniformity of the magnetic field within a certain range by replacing the pole head of the electromagnet, and the size of the magnetic field can be changed by adjusting the distance between the pole heads. This type of electromagnet can be well compatible with the magnetic field platform designed by customers.

2. The magnetic field of a monotonically variable air gap electromagnet is unidirectionally adjustable, with a closed magnetic circuit composed of two Eritreans and good rigidity. The direction of the magnetic field is vertical; Standing upright, the sample can be placed on the plane of the lower pole head, making it convenient to take and place the sample, suitable for multiple repeated measurements.

  3. The majority of multipolar electromagnets are quadrupole electromagnets, as well as five pole, six pole, eight pole and other multipolar applications. They are mainly used for multipolar magnetic ring magnetization, radial gradient magnetic field, rotating magnetic field magnetic guidance and other applications. They are designed and manufactured according to the user's requirements. This type of electromagnet can be completely compatible with the magnetic field platform designed by the customer.

4. Rotating magnet, the magnetic field can rotate 360 ° around the rotating shaft, and can be equipped with a stepper motor to accurately control the rotation of the magnet. The rotation angle can be set arbitrarily, and the forward and reverse rotation and travel time can be programmatically controlled. The angle resolution accuracy of the controller is 0.01 degrees, the mechanical step angle accuracy is 0.1 degrees, and the repeated positioning accuracy is 0.05 degrees.

            When conducting scientific experiments, sometimes normal types of electromagnets cannot meet the usage needs, so it is necessary to customize various shapes of electromagnets to meet different experimental needs. For example, clamp type electromagnets have bipolar protruding wires on the outer side of the package, with a shape like a clamp. They are usually used to generate in-plane magnetic fields and are suitable for special use environments such as microscopes, probe stations, limited space, magneto optical experiments, and magnetic ore powder screening. Our company can design and produce various shaped and special purpose electromagnets according to user requirements. Design and production can be carried out according to different usage methods, different experimental requirements, different working environments, and matching assembly with different equipment; It can achieve great deformation of the electromagnet while maintaining a high magnetic field.
