Magnetic hook
A magnetic hook consists of a tapped neodymium magnet into which a steel hook is screwed. The magnet is encapsulated in a steel shell, which redirects the magnetic field only to the hook base while increasing the magnetization power.
The magnetic hook category includes magnets with single hook, rotating hook, eyelet or carabiner, as well as hooks screwed on magnetic anti-slip pad, and magnetic coat hangers.
Size and power of magnetic hooks
Like all magnets, the magnetic hooks that you will find in this category magnetize on surfaces containing iron or steel.
We indicate for each hook a magnetization power in pulling force and a sliding force power, which corresponds to the resistance of the magnet on a vertical support (The weight then slides the magnet down, significantly reducing its magnetization power).
These powers are indicated in optimal magnetization conditions, when the hooks are in direct contact with a sufficiently thick iron support. Consider the impact of sliding forces to know which hook you will need.
Why a steel shell for magnetic hooks?
The steel shell around the magnet prevents the magnetic field from spreading at 360°, it is only active at the base of the magnet. The magnetic field is stronger, which considerably increases the magnetization power compared to a magnet without a steel shell.
Another advantage is that the steel shell protects the magnet from shocks.
Like all magnets, magnetic hooks in a steel shell lose 90% of their effectiveness on vertical surfaces due to the sliding forces. For this kind of use, choose magnetic anti-slip hooks instead
Simple magnetic hook or anti-slip?
The anti-slip magnetic hooks are attached to resin magnetic pads, containing several very powerful neodymium magnets. The roughness of the resin greatly increases the contact points between the stud and the ferrous support, which decreases the impact of sliding forces.
The anti-slip pads will be more effective than the raw magnetic hooks on vertical surfaces.
