The SI unit for magnet flux is (Wb) weber. However, if the magnet flux variation in 1 second, produces 1 V of electromotive force in a coil, this flux will correspond to 1 Wb. Therefore, 1Wb = 1 Vs (voltage-second).

Wooden core electromagnet vs iron core electromagnet?
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet. The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This does not happen with nonmagnetic materials such as wood or aluminum or rubber. The enhancement of the electromagnet is caused by the magnetic properties of iron. The atoms of iron have magnetic properties as a consequence of thier electronic structure. (The cause of magnetism at the atomic level is a complex issue if described in detail and that complexity is beyond this explanation.) In a simplified picture one can say that at the atomic level the iron atoms act like little magnets. The magnetic characteristics of iron are such that an external magnetic field causes the rearrangement of the electronic structure of the iron at the atomic level and that creates a magnetization in the iron. That magnetizations has its own magnetic field just like a normal permanent magnet. The field created by the magnetization of the material adds to the external field and one gets a stronger magnetic field in and around the iron core.
What happens when a bar magnet is thrust into a coil?
When a bar magnet is thrust into a coil, the magnetic field of the magnet will "sweep" across the wire in the coil and induce a voltage in that coil. This is called induction, and if the coil is connected to an external circuit, there will be current flow in that circuit.

Why do magnets attract or repel each other even when they are held apart?
Many things are magnetic, though in varying degrees, especially special rocks called magnets. Magma, lava underneath the surface of the earth, is highly magnetic, as lava often comes out in special areas on the surface forming a visible magnetic field. Humans are made from soil/dirt, and we have the same minerals in us as the earth does, and since the earth is magnetic, so are we, and scientists have proven that recently. They have found that we have ultramicroscopic minerals in our heads or in our brains that are magnetic, though they don't work the same way as the magnets in animals function. Animals navigate, especially during migration, due to the magnetic field of the earth, like a compass, and God designed them just for that. Also, you can make a makeshift compass by finding a small piece of light metal wire and rubbing it on your head to get static electricity. Now that it is magnetized, place it on a leaf in a pool of water, and it will align like a compass does! All thanks to Bear Grylls and his show of Man vs. Wild on Discovery channel!

How can hysteresis loss in magnetic material may be reduced?
Hysteresis losses depend on the type of metal used to manufacture the magnetic circuit of a machine. Most magnetic circuits are made from silicon steel. Generally speaking, there's not much you can do to reduce hysteresis losses as that has already been factored in by the machine's designer.
What is a footcandle vs a footlambert?
A footcandle is a unit of measurement for illuminance on a surface, equal to one lumen per square foot. A footlambert, on the other hand, is a unit of luminance, measuring the brightness of a surface emitting or reflecting light in footlamberts.
How like charges or magnetic respond?
Like charges or magnetic fields repel each other. Like terms means ex. N. Pole of a magnet vs N. Pole of a magnet S. Pole of a magnet vs S. Pole of a magnet
