Fielect 10Pcs Toroid Core Ferrite Choke Iron Powder Inductor Ferrite Ring 24.1x39.9x14.5mm，Black

【Parameters】 -Product model:T157-125A.
【Material】 - The toroid transformer is made of ferrite, this is a ferrite ring, not a magnet. It has no magnetism.
【Features】 -The iron powder core has the characteristics of eddy current isolation, low magnetic permeability and interference suppression.
【Function】 - Toroid core can not only reduce electromagnetic interference but also improve signal integrity.
【Application】 -Ferrite rings are often used to suppress the interference of power lines and signal lines, and at the same time have the ability to absorb electrostatic pulses.

Includes 2 magnets (.75 inch disc magnet and 1 inch bar magnet) and 1 filing-filled tray measuring 3.44 inches in diameter. The small bar magnet has color coded poles (red north and blue south)..
Features scratch-resistant plastic, rubber-coated magnets, and clean steel flings for clear viewing! Filings are sealed inside a mess-free, transparent viewing tray made of special scratch-resistant plastic that stands up to classroom use. Steel filings (cleaner than iron filings) ensure cloud-free viewing. Magnets are rubber-coated to prevent scratching of the viewing tray..
View a magnet’s invisible lines of force and manipulate it with our own hands! Place a magnet under the dish. Gently shake the dish. Tip the dish to one side, so the extra flings inside fall away from the magnet. Notice how certain areas of the magnet attract more filings. Those areas are the magnet’s poles. How do the areas of attraction of the disc magnet differ from those of the bar magnet? Where are the disc magnet’s poles? Where are the bar magnet’s poles? “Breaks” in the pattern of the filings inside the dish indicate the separations between the poles of the magnet..
Explore the basics of magnetism (attraction, repulsion, polarity, and more). US safety tested fo....
