Glass fibers are commonly added to nylon, polypropylene and other polymers to make glass-fiber reinforced plastic (GFRP) that is stiffer and stronger than unfilled polymer. Short-glass fiber (SGF), which is chopped into lengths of less than one-half inch, improves stiffness and impact strength ...
When two metals are attracted to each other across space, one or both of them are probably magnetic. You may be most familiar with permanent magnets, which are stronger magnets because they have iron in them. This type of magnetism is calledferromagnetism. The Earth's magnetic field is caused...
Like magnetic poles repulse one another while opposite magnetic poles attract. Magnets are naturally drawn to higher magnetic fields. Think of having two magnets, one at 10 tesla and one at 1 tesla. The 10 tesla magnet exerts a stronger magnetic field. A piece of magnetic material, placed equ...
Marketing automation is the engine that makes segmentationand personalisation possibleat scale. Today’s marketing automation platforms allow businesses to segment audiences by a number of identifiers, such as age, location, interests, and purchasing history. This approach to email marketing means customer...
Not only are neodymium magnets stronger, magnetically, than ceramic magnets; they are harder as well. Ceramic magnets are brittle, making them susceptible to damage. If you drop a ceramic magnet on the ground, there’s a good chance it will break. Neodymium magnets, on the other hand, are...
And in doing so, I became that much stronger when tackling future challenges. 5. Side hustle — finding a way to make a hobby pay for itself S: I've always loved nature photography, but it's an expensive pastime. I wanted to see if I could earn enough money doing what I love. ...

Which is a brittle material that is stronger than most metals and is commonly used in magnets? a. alloy b. ferrite c. nickel d. cobalt What is a transistor composed of, and what are some of its functions? Which isotope would you expect to be radioactive? 40 20 C a or 45 20 C a...
Do permanent magnets lose their magnetism? What makes an object magnetic according to the Pauli exclusion principle? What is the sure test for magnetism? What are the properties of a magnetic field? Why is there no magnetic force on a stationary charge? Does magnetism go through iron? Why are...
Ferrimagnetism: Like ferromagnets, ferrimagnetsretain magnetizationwhen removed from a magnetic field but neighboring pairs of electron spins point in opposite directions. The lattice arrangement of the material makes the magnetic moment pointing in one direction stronger than that pointing in the other ...
