Why must soft iron be used with an electromagnet?Suppose that a (small) charged conductor is connected to the ground. Explain why the conductor becomes uncharged.Why are magnetic field lines closed curves?Why are metals good conductors of heat and electricity?Why is Earth's magnetic field weake...
Explain why a soft-iron core increases the strength of an electromagnet. Why does increasing the temperature of a magnet decrease its magnetism? Why did the solar nebula flatten into a disk? Why nanoparticles have quantised properties? What is a nuclei? Explain why a protostar heats ...
If either of these fails, it can cause shifting problems with any gear, including the 3rd gear, so it’s most likely a bad shift electromagnet. Shift solenoid tubes are most commonly achieved by removing the valve body, which is done by removing the car’s transmission oil pan, but in...
In the 1920s the speaker was often a large full-range horn.1940sIn the 1940s these single horns evolved into one large DC-electromagnet woofer in a very large cabinet, with a large high-frequency horn tweeter on top. 1950sThe 1950s brought us 15" horn-loaded permanent-magnet woofers ...
When an AC voltage is applied to the pair of coils, an electromagnetic field of opposite charges is created. The fields extend to each other across a plane of the conductive rotor, creating an electromagnet with a north and south pole. This activityinducesa current to flow on...
Additionally, the armored chestplate powered the electromagnet (the famous arc reactor in the films) that prevented deadly shrapnel from reaching his heart; thus, both the suit and the electromagnet were designed with the sole purpose of keeping Stark alive. The Iron Man armor was never designed ...
How do you know if mechanical energy is conserved? Explain the energy transformation processes in an electromagnet. How does energy travel in a mechanical wave? Why does the electromagnetic force become weaker at higher energies? Give a physical interpretation and real ...
These are cubic, tetragonal, hexagonal, rhombic, monoclinic, and triclinic. Answer and Explanation: The most efficient technique to determine the crystallinity of solid material is using x-ray diffraction. Since an x-ray can penetrate solid objects,......
A) What is an electromagnet? B) What causes the magnetic field of the earth? C) What causes the northern and southern lights? What is magnetic intensity? Is the magnetism in bar magnet permanent or temporary? What happens when earth's magnetic field flips? Lightning is an...
