Suggested Amperage for electromagnet

Ask an Expert Topic Forum: Grades 9-12: Physical Science

Suggested Amperage for electromagnet Suggested Amperage for electromagnet Hello, I am a Sophomore student working on my science fair project. I am applying varying magnetic field strengths to plasmas to see how the voltage change over the ionized gas. My theory is that if ionized gas is condensed into a tighter stream, the energy will flow easier through the ions. I am using a type of cathode-ray tube to form the plasma. I am still unsure what the range of amperage should be for the small… Read more

Dilution of An Enzyme Solution

Ask an Expert Topic Forum: Grades 9-12: Life, Earth, and Social Sciences

Dilution of An Enzyme Solution Dilution of An Enzyme Solution Hello, My science fair project aims to find out how diluting an enzyme solution will affect its reaction. If I were to make a 10% dilution, would it be 1 part of the enzyme solution to 10 parts distilled water or just 10% distilled water added to the enzyme solution that was created in the experiment? Another question I have is, would the undiluted solution be just the enzyme solution without distilled water? If I could receive… Read more
