Some Function Generator has a Sweep option.
What exactly does the Sweep do?? What is it good for?
Tnx.

The sweep function will set the generator to automatically sweep across
a range of frequencies (usually programmable in some way).
For instance, setting the sweep range for 100Hz to 1kHz with a sweep
time of 10msec will cause the generator to output a signal starting at
100Hz, increasing to 1kHz in a time of 10msec.
This is extremely useful for evaluating circuits across their expected
frequency range (and especially filters, although that's only one
possible target) for amplitude and phase response, amongst other
things.
There are many uses for sweep generators, which is why the
functionality for them varies widely. Read the data sheets closely to
see just what is available on the units you may be interested in.

I see. Thanks.
I need a function generator with 50 volts. Normal ones only have
9 volts. Why do they limit it to just 9 and how much difficult
to make it 50 or so.
Another thing.
Suppose I set the function gen to 10Hz Sine Wave.. and I use
some coils in the output, can the coil produce magnetic fields?

It not only can, you would be hard put to prevent it. But how much
field strength do you need?
Suppose my function generator has 10 volts maximum. Can I
use an external 50 volts to ride on the 10 volts signal
so that the ouput of the external 50 volts is tuned in to
say the 20 hz sine wave (or other waveshapes) of the function
generator?
