Calculating Current & Voltage in Coil with Magnet

[Swifters]

I have been wondering how to calculate how much current and voltage would be induced through a 2m length of coil when a magnet passes through. The coil being 30mm in diameter with 1mm thick wire coiled around 200 times (for ease of calculation so cable would roughly be 18.8m long) with a resistance of say 16 ohms. Magnet being a cylindrical sphere of just under 30mm diameter... This is not homework, just wondered if there was a formula? many thanks.

Dosent have to be precise. Any rough estimate will do. Thank you.

"Magnet" is an unknown variable in this hypothetical. Magnitude of magnetic flux field is critical for calculating induced current.

Magnetic flux? Is that the strength of the magnet? What if it were presumed to be average? Is there a formula?

any ideas most welcome...
