In Yu-Gi-Oh my friend played 'Light Barrier' and the next turn I drew a 'Magic Jammer'. The next turn to keep 'Light Barrier's effect to work he has to toss a coin is that activating the card?
There is an important distinction between 'activating a spell/trap' and 'activating the effect of a spell/trap'. Light Barrier's activation was when it was placed face-up on the field, and this is the only time an activation negation card like Magic Jammer could be used against it. Then after they have resolved to the field, some of them have a reusable effect, this is not activating the card, just activating the effect.Later on, even if it has an effect that uses the chain (Light Barrier's does), this is only activating the 'effect' of Light Barrier, he is not 'activating Light Barrier', therefore Magic Jammer can not be used at this time.
