What's the theoretical potential for how strong electromagnets can get? If you just kept coiling a solenoid longer and wider, and fed more and more current into the coil, would the field strength i...

Mar 26, 2025 · The strength of an electromagnet can be determined by analyzing the number of wire turns, the strength of the current, and the core material. Practical tests include measuring the amount …

Dec 5, 2023 · When an object is placed in the field of a strong electromagnet connected to an AC line, it can be attracted or repelled depending on the polarity of its magnetic field.

Dec 20, 2023 · The object placed in a strong electromagnet's field connected to an AC line may become magnetized or demagnetized, depending on its initial state. Additionally, conductive objects can be …

Jul 30, 2022 · To get a reasonably strong electromagnet you need many more turns (may be a few hundreds). It is a good idea to use an iron core (like your screw) to make a strong electromagnet.

Jul 19, 2019 · A strong electromagnet produces a uniform magnetic field of 1.60 T over a cross-sectional area of 0.340 m 2. A coil with 190 turns and a total resistance of 16.0 Ω is placed around the …

An electromagnet was connected to a 12v battery and I verified that it was working. I then touched the electromagnet to a strong regular magnet (rated to hold over 50 kg). There was a strong force …

Nov 10, 2016 · Which statement about an electromagnet is true? It doesn’t function without a source of current. The core is made from a nonmagnetic material. It uses moving magnets to create an electric …

I'm working on a science project and need to know what makes a strong electromagnet - more wire turns or more voltage? I understand energy can be lost to heat with too many wire turns.

Nov 9, 2024 · Select the correct answer. Which statement about an electromagnet is true? A. It doesn't function without a source of current. B. The core is made from a nonmagnetic material. C. It uses …
