What is a magnetic base?

A magnetic base uses soft magnetic material that rapidly magnetizes and demagnetizes in a weak magnetic field, enabling strong adhesion or quick release on metal surfaces.
A handle switches the polarity of the magnet. The base adheres to steel when magnetized, and is virtually non-magnetic when horizontal, making it easy to attach and detach.
This device is commonly used to secure measuring instruments, tools, or workpieces, providing stable support without being restricted by threaded hole placement.

Main Structure and Function of a Magnetic Base (Based on the provided magnetic stand image)

1. Base: A square base with an embedded permanent magnet and a magnetic switch knob for controlling adhesion and release.

2. Universal Joint: A spherical or universal joint connecting the base and arm, allowing for multi-directional rotation in horizontal, vertical, and tilt directions for flexible positioning.

3. Arm: A metal or high-strength plastic rod that extends and supports, can bend or bend to adjust the working range, and transmits support force to the measurement point. 4. Adjustment Knob: Located on the joint or arm, this knob locks the joint to prevent vibration-induced positional deviation and ensures stability during measurement.
5. Clamping Device: The top-mounted adjustable chuck is designed specifically for instruments such as dial and micrometer indicators, providing reliable clamping force and quick installation and removal.
How to Place the Magnet on the Base?

1. Turn on the magnetic switch: Turn the magnetic switch knob on the side of the base to de-magnetize the internal permanent magnet, eliminating its attraction to the base surface.
2. Place the Magnet: Align the north or south pole of the magnet with the magnetic surface in the center of the base and gently place it on the base.
3. Activate Magnetization: Turn the switch again to align the magnet's polarity with the base's magnetic circuit. The base is instantly magnetized, generating a strong attraction that securely attaches the magnet to the metal surface.
4. Check for Stability: Gently pull on the magnet to confirm it is firmly attached. You can then install a measuring instrument or perform machining positioning.
