When lines of force are cut by a conductor you have magnetic?
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
Why transformer action can take place in DC and ac circuit?
First understand that every electrical conductor (wire) with current flow through it will produce an invisible magnetic field around it. This field is directly proportional to the magnitude of current flowing. Second (and inversely) realize that any conductor moving through a magnetic field will produce a voltage, And if provided with a complete circuit (a path to flow in) will result in current flow in that conductor. The movement can be from the conductor moving, or from the magnetic field moving, as long as there is 'relative motion' between the conductor and the magnetic field. In short, a conductor with current flow produces a magnetic field , a conductor and a magnetic field with relative motion between them produces current flow. (This is also the basis for how a motor works) AC means 'Alternating Current'! The current flow moves in one direction along a conductor, then reverses to zero and to equal magnitude in the opposite direction. Each time this current changes direction it produces a magnetic field, as it returns to zero the field collapses. As the current builds in the opposite direction the magnetic field builds again. In an AC transformer circuit, two conductors are placed in close proximity to each other and an alternating current is applied to the first conductor. This alternating current causes a magnetic field to build around the conductor, then collapse, build again in the opposite polarity and so on. This expanding and collapsing magnetic field creates relative motion between the field and the second conductor which then produces current flow of its own. This is called "transformer Action". In steady state DC circuits, the magnetic field is constant and there is normally no relative motion, therefore no "transformer action". There is however still a relative motion created when the circuit is first energized, and when it is de-energized. This collapsing field is how the ignition coil in your car works. In the simplest form, contacts (points) were opened by a cam, the open contacts de-energized the first conductor (the 12VDC primary). The resulting collapsing field cut across the secondary conductors. Because these conductors were wound into many turns or "coils" it actually multiplies the effect producing a high voltage in the secondary (connected to the ignition wires). This produced a voltage and current strong enough to jump across the gap of a spark plug. And, Yes Virginia, there is such a thing as a DC transformer.
What three factors affectthe size of induced emf?
If you are referring to the voltage induced into a conductor moving through a magnetic field, then the FOUR (not three) factors are (a) the flux density of the field (teslas), (b) the velocity of the conductor (metres per second), (c) the angle at which the flux is being cut, and (d) the length of the conductor within the field.
Can a vacuum is conductor or non conductor?

When lines of force are cut by a you have electromagnetic induction?
When lines of force are cut by a conductor you have electromagnetic induction. A metallic wire can be used as the conductor.
What is an accepted method of isolating hazardous energy sources within a confined space?
performing lockout/tagout (LOTO) on an energized electrical conductor
What is a rccb?
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric currents not balanced between the energized conductor and the return neutral conductor.

What do you do after you cut the wires?
If the wires were cut purposely then cap and tape the ends in case they become inadvertently energized. If the wires were cut inadvertently, the wires can be butt spliced together and retaped to bring the insulation factor up to what it was before the cut.

Can we cut live conductor when current is passing?
You should never cut a live conductor. If it's a single conductor, you may be subject to a shock hazard to earth (ground). If it's a pair of conductors, then you will be creating a short circuit and may be burnt by the resulting arc.

What does a fermata tell a performer to do?
Hold the note longer - if there is a conductor then wait for his/her cut
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
