Product Description

Overview

 

   Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When one on the end is lifted and released, the resulting force travels through the line and pushes the last one upward. The device is also known as an executive ball clicker, Newton's balls, or Newton's pendulum construction.

 

    A typical Newton's cradle consists of a series of identically sized metal balls suspended in a metal frame so that they are just touching each other at rest. Each ball is attached to the frame by two wires of equal length angled away from each other. This restricts the pendulums' movements to the same plane.

FAQ

FAQ

1.Do you provide samples ? is it free or extra ?

Yes, we could offer the sample for free charge if we have stock, but do not pay the cost of freight.

 

2.Is it OK to print my logo on magnet product or package?

Yes. Please inform us formally before our production and confirm the design firstly based on our sample.

 

3.How long does it take for production and shipping duration?

For regular magnet orders: 5-7 working days customized items, it would take 7-15 working days or so. Besides, the fastest production time is 3working days for the urgent orders.

 

4.How does the magnet grade and magnet dimensions (L x W x H) affects the Gauss grade of magnets?

Same magnet size, higher grade with higher gauss; Same magnet grade, same surface area, the thicker, the higher gauss;
Same magnet grade, same thickness, larger surface area with lower gauss;

 

5.What does pulling force mean?

Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid magnetic surface, such as a steel plate.

 

6.If I stick two neodymium magnets together, does their strength double?

No. It will a little smaller. For example, two magnets rated with a individual pulling force of 50 lbs will have a combined pulling force of 90 lbs when stick together.

 

7.Do neodymium magnets lose strength over time?

They don'tnaturally lose any strength and will keep the strength permanently in the normal conditions, unless meet the high temperature over 80 degrees Celsius(ºC), and then will lose the strength gradually.

 

8. What materials do magnets attract?

Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron (Fe), nickel (Ni), and cobalt (Co) are themost commonly available elements. Steel is ferromagnetic because it is an alloy of iron and other metals.

 

9.How do you make our business long-term and good relationship?

a) We keep good quality and competitive price to ensure our customers benefit ;

b) We respect every customer as our friend and we sincerely do business and make friends with them
