Wrap the rod in magnetic wire (see Resources). Start at one end and wrap the wire all the way to the other end. Cut the wire, leaving several inches of loose wire hanging off either end. Wrap it as tightly as you can. The tighter the wire wrapping, the stronger the magnetic field....
How is a magnetic field produced in a current-carrying conductor? What are the characteristics of a magnetic field? How to make a magnetic field stronger. Why is the magnetic force perpendicular to the magnetic field? How can a permanent magnet lose its magnetism?
To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other ways to align magn...

Generally, we tend to brushless motors as they are more durable and powerful, while brushed motors are often used in cheap toy drones as they are more cost effective to make. In this guide, we’ll be focusing solely on brushless motors, which are the go-to choice for modern FPV drones....
You can also try increasing the size of the armature, and how many coils there are, to make a stronger electromagnet. When using batteries of higher voltage, and bare wires, be very careful. The circuit can emit enough heat to cause a burn if the wire is held too long. More Electricity...
如何让自己的气场熠熠发光(How to make their aura shining) How to make their "aura" shining? What is gas field? In short, personal aura refers to the personal charm of a person's character, demeanor, and personality. A good gas field is a key to open the door to a happy life. So,...
Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, however concentrates the magnetic field. Each coil of wire contributes a small magnetic field and, together, they add up to make a much more powerful magnet...
