Magnets : Neodymium Magnets C

Are Cup Magnets Stronger?

Cup magnets feature a round shape with a flat bottom that makes mounting them simple using screws, bolts, rivets or epoxy through countersunk holes. Not only are these strong magnets versatile; but also use for many other applications!

Strong Neodymium Pot Magnets are ideal for organizing your workspace, holding objects and tools securely in place and can withstand high amounts of force without bowing under pressure.


Neodymium magnets are rare-earth magnets crafted from neodymium, iron and boron elements combining for powerful magnetism at small sizes. Their combination allows these magnets to achieve higher magnetic super-strength at smaller sizes - ideal for industrial as well as personal uses. In addition, their resistance to demagnetization makes them even longer-lived than ceramic or ferrite magnets; making these ideal solutions for long-term applications.

Neodymium magnets are typically coated with nickel, copper and zinc plating to protect them from corrosion; without this protection neodymium is more prone to oxidization and breakage.

These types of magnets use steel pots designed to channel and increase magnetic force in a specific direction, which makes these powerful and suitable for mounting solutions where space is limited or strong adhesive forces are needed - hence why these types of magnets are often known as pot or mounting magnets.


Ceramic magnets offer low costs and resistance to demagnetization, making them suitable for sensors and motors as well as resisting temperature variations and corrosion. Unfortunately, however, they must be handled carefully due to being fragile.

Cup magnets consist of a ceramic disc magnet enclosed within a steel cup to increase magnetic pull force and save space, ideal for use in channels and cups that cannot accommodate regular magnets. They can be attached directly to workpieces via countersunk holes.

Iron shell magnets alter the original magnetic circuit to focus the magnetic energy at one location for even stronger pulling force, making these types of magnets more powerful than their regular counterparts. Ideal for science and craft projects, but should not be used with machinery that requires stress or flexing as they may demagnetize at high temperatures.


Strength of neodymium magnets can be significantly increased by placing them inside a steel cup or channel. This allows one pole of the magnet to adhere directly to metal surfaces, significantly increasing its magnetic strength. Furthermore, magnets enclosed within these cups or channels are capable of focusing their magnetic force directly onto an adhesive surface at direct contact for much higher adhesive forces than standalone neodymium magnets.

Magnetic channels and cups can be equipped with threaded studs, hooks or countersunk holes for mounting purposes - making them suitable for many mounting, fixing and holding needs across industries and workplaces.

When selecting a mounting magnet, it's important to remember that the pull force numbers we provide apply only when pulling away directly from a steel surface. When loaded differently than this number indicates, their actual holding strength may decrease due to being attached directly onto steel surfaces where magnetic fields become redirected and thus decrease holding strength over time.

Iron Shell

These pot magnets produce up to ten times greater magnetic force than similar ceramic or other magnets, meaning a small neodymium magnet can replace much larger one while still creating holding power equivalent to what would normally be found with ceramic magnets.

Reverse-polarity magnets are created by adhering round neodymium magnets to iron shells using glue, in order to protect them from breaking. Steel pots also help amplify magnetic forces by concentrating them onto one face of the magnet - this increases magnetic forces up to twice as strongly compared with flat neodymium magnets.

Pot magnets are widely used for mounting purposes, particularly heavy duty hanging tasks like supermarket ceiling signs. Because their production does not require precise craftsmanship or high precision measurements, pot magnets can be manufactured quickly and cheaply through stamping processes for daily tasks such as mounting signs. Though pot magnets do contain two magnetic poles - north and south poles - their iron shell conceals one pole so it appears as though there's only one magnetic pole present.
